This document is primarily + a reference to help people who are interested in our project accessibility support and will describe how to use VirtualBox + user interface step-by-step. Since whole the application navigation will be explained here, this document will also be + helpful for those who are not familiar with our product user interface and wish to learn more. It will be written in a bit + excessive manner so that many obvious things will be explained too precisely to make it easier to understand by ear for a + blind users. The document will be periodically updated with recent changes and test-cases allowing us to more strictly + follow the required guidelines and make our product fully accessible. + </para> + <para> + Our application is based on Qt5, a powerful cross-platform library which allows to visualize various user interface ideas + the most flexible and native way. This also means that the library we use is responsible for many navigation and + accessibility aspects (like fonts, size hints, colors, look&feel patterns and many other things), but not for all of + them. Nativity as one of the main ideas of the Qt-based application sometimes brings additional complexity because there is + always at least one host which uses unique combination of fonts and colors which breaks accessibility support in an + unpredictable way. + </para> + <para> + Independently on platform we are supporting screen-reader applications which can communicate with Qt5 accessibility + interface which supports Microsoft Active Accessibility (MSAA), OS X Accessibility, and the Unix/X11 AT-SPI standard. + </para> + <para> + Our application user interface is able to be started in two modes: + <itemizedlist> + <listitem> + <para> + First of them is <emphasis role="bold">VirtualBox Manager</emphasis> user interface, the main application window + which allows to manage and configure virtual machines and their groups.

Besides that, this interface allows to access some of + machine tools and adjust guest screens up to your needs, by changing their resolution and toggling full-screen, + seamless and scaled modes. + </para> + </listitem> + </itemizedlist> + But first of all we should start from the <emphasis role="bold">General Concept</emphasis> which is related to whole the + GUI and summarizes the navigation and accessibility aspects we are using for whole application. + </para> + </chapter> + + <chapter> + <title>General concept</title> + <para> + This chapter describes the general navigation and accessibility concept.

For example, the RDP server, which can deliver the + graphical output of a VM remotely to an RDP client, is a separate module + that is only loosely tacked into the virtual graphics device. Live + Migration and Resource Monitor are additional modules currently in the + process of being added to VirtualBox.</para> + + <para>What is primarily of interest for purposes of the SDK is the API + layer block that sits on top of all the previously mentioned blocks. + This API, which we call the <emphasis role="bold">"Main API"</emphasis>, + exposes the entire feature set of the virtualization engine below. It is + completely documented in this SDK Reference -- see <xref + linkend="sdkref_classes"/> and <xref linkend="sdkref_enums"/> -- and + available to anyone who wishes to control VirtualBox programmatically. + We chose the name "Main API" to differentiate it from other programming + interfaces of VirtualBox that may be publicly accessible.</para> + + <para>With the Main API, you can create, configure, start, stop and + delete virtual machines, retrieve performance statistics about running + VMs, configure the VirtualBox installation in general, and more. In + fact, internally, the front-end programs + <computeroutput>VirtualBox</computeroutput> and + <computeroutput>VBoxManage</computeroutput> use nothing but this API as + well -- there are no hidden backdoors into the virtualization engine for + our own front-ends. This ensures the entire Main API is both + well-documented and well-tested.

The web + service ships in a stand-alone executable + (<computeroutput>vboxwebsrv</computeroutput>) that, when running, + acts as an HTTP server, accepts SOAP connections and processes + them.</para> + + <para>Since the entire web service API is publicly described in a + web service description file (in WSDL format), you can write + client programs that call the web service in any language with a + toolkit that understands WSDL. These days, that includes most + programming languages that are available: Java, C++, .NET, PHP, + Python, Perl and probably many more.</para> + + <para>All of this is explained in detail in subsequent chapters of + this book.</para> + + <para>There are two ways in which you can write client code that + uses the web service:<orderedlist> + <listitem> + <para>For Java as well as Python, the SDK contains + easy-to-use classes that allow you to use the web service in + an object-oriented, straightforward manner. We shall refer + to this as the <emphasis role="bold">"object-oriented web + service (OOWS)"</emphasis>.</para> + + <para>The OO bindings for Java are described in <xref + linkend="javaapi"/>, those for Python in <xref + linkend="glue-python-ws"/>.</para> + </listitem> + + <listitem> + <para>Alternatively, you can use the web service directly, + without the object-oriented client layer. We shall refer to + this as the <emphasis role="bold">"raw web + service"</emphasis>.</para> + + <para>You will then have neither native object orientation + nor full type safety, since web services are neither + object-oriented nor stateful. However, in this way, you can + write client code even in languages for which we do not ship + object-oriented client code; all you need is a programming + language with a toolkit that can parse WSDL and generate + client wrapper code from it.</para> + + <para>We describe this further in <xref + linkend="raw-webservice"/>, with samples for Java and + Perl.</para> + </listitem> + </orderedlist></para> + </listitem> + + <listitem> + <para>Internally, for portability and easier maintenance, the Main + API is implemented using the <emphasis role="bold">Component + Object Model (COM), </emphasis> an interprocess mechanism for + software components originally introduced by Microsoft for + Microsoft Windows. On a Windows host, VirtualBox will use + Microsoft COM; on other hosts where COM is not present, it ships + with XPCOM, a free software implementation of COM originally + created by the Mozilla project for their browsers.</para> + + <para>So, if you are familiar with COM and the C++ programming + language (or with any other programming language that can handle + COM/XPCOM objects, such as Java, Visual Basic or C#), then you can + use the COM/XPCOM API directly.

For an introduction, please see <xref + linkend="api_com"/> below.</para> + + <para>The VirtualBox front-ends (the graphical user interfaces as + well as the command line), which are all written in C++, use + COM/XPCOM to call the Main API.

However, while these previous + technologies relied on specific binary protocols and thus proved to + be difficult to use between diverging platforms, web services + circumvent these incompatibilities by using text-only standards like + HTTP and XML. On the downside (and, one could say, typical of things + related to XML), a lot of standards are involved before a web + service can be implemented. Many of the standards invented around + XML are used one way or another. As a result, web services are slow + and verbose, and the details can be incredibly messy. The relevant + standards here are called SOAP and WSDL, where SOAP describes the + format of the messages that are exchanged (an XML document wrapped + in an HTTP header), and WSDL is an XML format that describes a + complete API provided by a web service. WSDL in turn uses XML Schema + to describe types, which is not exactly terse either. However, as + you will see from the samples provided in this chapter, the + VirtualBox web service shields you from these details and is easy to + use.</para> + </footnote></para> + + <para>In order to successfully use a web service, a number of things are + required -- primarily, a web service accepting connections; service + descriptions; and then a client that connects to that web service. The + connections are governed by the SOAP standard, which describes how + messages are to be exchanged between a service and its clients; the + service descriptions are governed by WSDL.</para> + + <para>In the case of VirtualBox, this translates into the following + three components:<orderedlist> + <listitem> + <para>The VirtualBox web service (the "server"): this is the + <computeroutput>vboxwebsrv</computeroutput> executable shipped + with VirtualBox. Once you start this executable (which acts as a + HTTP server on a specific TCP/IP port), clients can connect to the + web service and thus control a VirtualBox installation.</para> + </listitem> + + <listitem> + <para>VirtualBox also comes with WSDL files that describe the + services provided by the web service. You can find these files in + the <computeroutput>sdk/bindings/webservice/</computeroutput> + directory. These files are understood by the web service toolkits + that are shipped with most programming languages and enable you to + easily access a web service even if you don't use our + object-oriented client layers.

VirtualBox is a + complicated environment in which multiple processes compete for possibly + the same resources, especially machine settings.

When reading from the virtual + disk, &product-name; needs to look into the second differencing + image first, then into the first if the sector was not found, and + then into the original image. + </para> + + <para> + There can be an unlimited number of differencing images, and each + image can have more than one child. As a result, the differencing + images can form a complex tree with parents, siblings, and + children, depending on how complex your machine configuration is. + Write operations always go to the one <emphasis>active</emphasis> + differencing image that is attached to the machine, and for read + operations, &product-name; may need to look up all the parents in + the chain until the sector in question is found.

There are four privilege + levels, called rings, and the same instruction set is + supported, with the addition of several virtualization + specific instruction. Root mode is what a host operating + system without virtualization uses, and it is also used by a + hypervisor when virtualization is active. + </para> + </listitem> + + <listitem> + <para> + In non-root mode, CPU operation is significantly different. + There are still four privilege rings and the same instruction + set, but a new structure called VMCS (Virtual Machine Control + Structure) now controls the CPU operation and determines how + certain instructions behave. Non-root mode is where guest + systems run. + </para> + </listitem> + + </itemizedlist> + + <para> + Switching from root mode to non-root mode is called "VM entry", + the switch back is "VM exit". The VMCS includes a guest and host + state area which is saved/restored at VM entry and exit. Most + importantly, the VMCS controls which guest operations will cause + VM exits. + </para> + + <para> + The VMCS provides fairly fine-grained control over what the guests + can and cannot do. For example, a hypervisor can allow a guest to + write certain bits in shadowed control registers, but not others. + This enables efficient virtualization in cases where guests can be + allowed to write control bits without disrupting the hypervisor, + while preventing them from altering control bits over which the + hypervisor needs to retain full control. The VMCS also provides + control over interrupt delivery and exceptions. + </para> + + <para> + Whenever an instruction or event causes a VM exit, the VMCS + contains information about the exit reason, often with + accompanying detail. For example, if a write to the CR0 register + causes an exit, the offending instruction is recorded, along with + the fact that a write access to a control register caused the + exit, and information about source and destination register. Thus + the hypervisor can efficiently handle the condition without + needing advanced techniques such as CSAM and PATM described above. + </para> + + <para> + VT-x inherently avoids several of the problems which software + virtualization faces. The guest has its own completely separate + address space not shared with the hypervisor, which eliminates + potential clashes. Additionally, guest OS kernel code runs at + privilege ring 0 in VMX non-root mode, obviating the problems by + running ring 0 code at less privileged levels. For example the + SYSENTER instruction can transition to ring 0 without causing + problems. Naturally, even at ring 0 in VMX non-root mode, any I/O + access by guest code still causes a VM exit, allowing for device + emulation. + </para> + + <para> + The biggest difference between VT-x and AMD-V is that AMD-V + provides a more complete virtualization environment. VT-x requires + the VMX non-root code to run with paging enabled, which precludes + hardware virtualization of real-mode code and non-paged + protected-mode software. This typically only includes firmware and + OS loaders, but nevertheless complicates VT-x hypervisor + implementation.

This General Public License applies to most of + the Free Software Foundation's software and to any other program + whose authors commit to using it. (Some other Free Software + Foundation software is covered by the GNU Library General Public + License instead.) You can apply it to your programs, too. + </para> + + <para> + When we speak of free software, we are referring to freedom, not + price. Our General Public Licenses are designed to make sure + that you have the freedom to distribute copies of free software + (and charge for this service if you wish), that you receive + source code or can get it if you want it, that you can change + the software or use pieces of it in new free programs; and that + you know you can do these things. + </para> + + <para> + To protect your rights, we need to make restrictions that forbid + anyone to deny you these rights or to ask you to surrender the + rights. These restrictions translate to certain responsibilities + for you if you distribute copies of the software, or if you + modify it. + </para> + + <para> + For example, if you distribute copies of such a program, whether + gratis or for a fee, you must give the recipients all the rights + that you have. You must make sure that they, too, receive or can + get the source code. And you must show them these terms so they + know their rights. + </para> + + <para> + We protect your rights with two steps: (1) copyright the + software, and (2) offer you this license which gives you legal + permission to copy, distribute and/or modify the software. + </para> + + <para> + Also, for each author's protection and ours, we want to make + certain that everyone understands that there is no warranty for + this free software. If the software is modified by someone else + and passed on, we want its recipients to know that what they + have is not the original, so that any problems introduced by + others will not reflect on the original authors' reputations. + </para> + + <para> + Finally, any free program is threatened constantly by software + patents. We wish to avoid the danger that redistributors of a + free program will individually obtain patent licenses, in effect + making the program proprietary. To prevent this, we have made it + clear that any patent must be licensed for everyone's free use + or not licensed at all. + </para> + + <para> + The precise terms and conditions for copying, distribution and + modification follow. + </para> + + <para> + GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, + DISTRIBUTION AND MODIFICATION + </para> + + <para> + 0. This License applies to any program or other work which + contains a notice placed by the copyright holder saying it may + be distributed under the terms of this General Public License. + The "Program", below, refers to any such program or work, and a + "work based on the Program" means either the Program or any + derivative work under copyright law: that is to say, a work + containing the Program or a portion of it, either verbatim or + with modifications and/or translated into another language. + (Hereinafter, translation is included without limitation in the + term "modification".) Each licensee is addressed as "you". + </para> + + <para> + Activities other than copying, distribution and modification are + not covered by this License; they are outside its scope. The act + of running the Program is not restricted, and the output from + the Program is covered only if its contents constitute a work + based on the Program (independent of having been made by running + the Program). Whether that is true depends on what the Program + does. + </para> + + <para> + 1. You may copy and distribute verbatim copies of the Program's + source code as you receive it, in any medium, provided that you + conspicuously and appropriately publish on each copy an + appropriate copyright notice and disclaimer of warranty; keep + intact all the notices that refer to this License and to the + absence of any warranty; and give any other recipients of the + Program a copy of this License along with the Program. + </para> + + <para> + You may charge a fee for the physical act of transferring a + copy, and you may at your option offer warranty protection in + exchange for a fee. + </para> + + <para> + 2. You may modify your copy or copies of the Program or any + portion of it, thus forming a work based on the Program, and + copy and distribute such modifications or work under the terms + of Section 1 above, provided that you also meet all of these + conditions: + </para> + + <para> + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + </para> + + <para> + b) You must cause any work that you distribute or publish, that + in whole or in part contains or is derived from the Program or + any part thereof, to be licensed as a whole at no charge to all + third parties under the terms of this License. + </para> + + <para> + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you + provide a warranty) and that users may redistribute the program + under these conditions, and telling the user how to view a copy + of this License. (Exception: if the Program itself is + interactive but does not normally print such an announcement, + your work based on the Program is not required to print an + announcement.) + </para> + + <para> + These requirements apply to the modified work as a whole. If + identifiable sections of that work are not derived from the + Program, and can be reasonably considered independent and + separate works in themselves, then this License, and its terms, + do not apply to those sections when you distribute them as + separate works. But when you distribute the same sections as + part of a whole which is a work based on the Program, the + distribution of the whole must be on the terms of this License, + whose permissions for other licensees extend to the entire + whole, and thus to each and every part regardless of who wrote + it. + </para> + + <para> + Thus, it is not the intent of this section to claim rights or + contest your rights to work written entirely by you; rather, the + intent is to exercise the right to control the distribution of + derivative or collective works based on the Program. + </para> + + <para> + In addition, mere aggregation of another work not based on the + Program with the Program (or with a work based on the Program) + on a volume of a storage or distribution medium does not bring + the other work under the scope of this License. + </para> + + <para> + 3. You may copy and distribute the Program (or a work based on + it, under Section 2) in object code or executable form under the + terms of Sections 1 and 2 above provided that you also do one of + the following: + </para> + + <para> + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of + Sections 1 and 2 above on a medium customarily used for software + interchange; or, + </para> + + <para> + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a + medium customarily used for software interchange; or, + </para> + + <para> + c) Accompany it with the information you received as to the + offer to distribute corresponding source code.

By contrast, the GNU General + Public Licenses are intended to guarantee your freedom to share + and change free software--to make sure the software is free for + all its users. + </para> + + <para> + This license, the Lesser General Public License, applies to some + specially designated software packages--typically libraries--of + the Free Software Foundation and other authors who decide to use + it. You can use it too, but we suggest you first think carefully + about whether this license or the ordinary General Public + License is the better strategy to use in any particular case, + based on the explanations below. + </para> + + <para> + When we speak of free software, we are referring to freedom of + use, not price. Our General Public Licenses are designed to make + sure that you have the freedom to distribute copies of free + software (and charge for this service if you wish); that you + receive source code or can get it if you want it; that you can + change the software and use pieces of it in new free programs; + and that you are informed that you can do these things. + </para> + + <para> + To protect your rights, we need to make restrictions that forbid + distributors to deny you these rights or to ask you to surrender + these rights. These restrictions translate to certain + responsibilities for you if you distribute copies of the library + or if you modify it. + </para> + + <para> + For example, if you distribute copies of the library, whether + gratis or for a fee, you must give the recipients all the rights + that we gave you. You must make sure that they, too, receive or + can get the source code. If you link other code with the + library, you must provide complete object files to the + recipients, so that they can relink them with the library after + making changes to the library and recompiling it. And you must + show them these terms so they know their rights. + </para> + + <para> + We protect your rights with a two-step method: (1) we copyright + the library, and (2) we offer you this license, which gives you + legal permission to copy, distribute and/or modify the library. + </para> + + <para> + To protect each distributor, we want to make it very clear that + there is no warranty for the free library. Also, if the library + is modified by someone else and passed on, the recipients should + know that what they have is not the original version, so that + the original author's reputation will not be affected by + problems that might be introduced by others. + </para> + + <para> + Finally, software patents pose a constant threat to the + existence of any free program. We wish to make sure that a + company cannot effectively restrict the users of a free program + by obtaining a restrictive license from a patent holder. + Therefore, we insist that any patent license obtained for a + version of the library must be consistent with the full freedom + of use specified in this license. + </para> + + <para> + Most GNU software, including some libraries, is covered by the + ordinary GNU General Public License. This license, the GNU + Lesser General Public License, applies to certain designated + libraries, and is quite different from the ordinary General + Public License. We use this license for certain libraries in + order to permit linking those libraries into non-free programs. + </para> + + <para> + When a program is linked with a library, whether statically or + using a shared library, the combination of the two is legally + speaking a combined work, a derivative of the original library. + The ordinary General Public License therefore permits such + linking only if the entire combination fits its criteria of + freedom. The Lesser General Public License permits more lax + criteria for linking other code with the library. + </para> + + <para> + We call this license the "Lesser" General Public License because + it does Less to protect the user's freedom than the ordinary + General Public License. It also provides other free software + developers Less of an advantage over competing non-free + programs. These disadvantages are the reason we use the ordinary + General Public License for many libraries. However, the Lesser + license provides advantages in certain special circumstances. + </para> + + <para> + For example, on rare occasions, there may be a special need to + encourage the widest possible use of a certain library, so that + it becomes a de-facto standard. To achieve this, non-free + programs must be allowed to use the library. A more frequent + case is that a free library does the same job as widely used + non-free libraries. In this case, there is little to gain by + limiting the free library to free software only, so we use the + Lesser General Public License. + </para> + + <para> + In other cases, permission to use a particular library in + non-free programs enables a greater number of people to use a + large body of free software. For example, permission to use the + GNU C Library in non-free programs enables many more people to + use the whole GNU operating system, as well as its variant, the + GNU/Linux operating system. + </para> + + <para> + Although the Lesser General Public License is Less protective of + the users' freedom, it does ensure that the user of a program + that is linked with the Library has the freedom and the + wherewithal to run that program using a modified version of the + Library. + </para> + + <para> + The precise terms and conditions for copying, distribution and + modification follow. Pay close attention to the difference + between a "work based on the library" and a "work that uses the + library". The former contains code derived from the library, + whereas the latter must be combined with the library in order to + run. + </para> + + <para> + GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR + COPYING, DISTRIBUTION AND MODIFICATION + </para> + + <para> + 0. This License Agreement applies to any software library or + other program which contains a notice placed by the copyright + holder or other authorized party saying it may be distributed + under the terms of this Lesser General Public License (also + called "this License"). Each licensee is addressed as "you". + </para> + + <para> + A "library" means a collection of software functions and/or data + prepared so as to be conveniently linked with application + programs (which use some of those functions and data) to form + executables. + </para> + + <para> + The "Library", below, refers to any such software library or + work which has been distributed under these terms. A "work based + on the Library" means either the Library or any derivative work + under copyright law: that is to say, a work containing the + Library or a portion of it, either verbatim or with + modifications and/or translated straightforwardly into another + language. (Hereinafter, translation is included without + limitation in the term "modification".) + </para> + + <para> + "Source code" for a work means the preferred form of the work + for making modifications to it. For a library, complete source + code means all the source code for all modules it contains, plus + any associated interface definition files, plus the scripts used + to control compilation and installation of the library. + </para> + + <para> + Activities other than copying, distribution and modification are + not covered by this License; they are outside its scope. The act + of running a program using the Library is not restricted, and + output from such a program is covered only if its contents + constitute a work based on the Library (independent of the use + of the Library in a tool for writing it). Whether that is true + depends on what the Library does and what the program that uses + the Library does. + </para> + + <para> + 1. You may copy and distribute verbatim copies of the Library's + complete source code as you receive it, in any medium, provided + that you conspicuously and appropriately publish on each copy an + appropriate copyright notice and disclaimer of warranty; keep + intact all the notices that refer to this License and to the + absence of any warranty; and distribute a copy of this License + along with the Library. + </para> + + <para> + You may charge a fee for the physical act of transferring a + copy, and you may at your option offer warranty protection in + exchange for a fee. + </para> + + <para> + 2. You may modify your copy or copies of the Library or any + portion of it, thus forming a work based on the Library, and + copy and distribute such modifications or work under the terms + of Section 1 above, provided that you also meet all of these + conditions: + </para> + + <para> + a) The modified work must itself be a software library. + </para> + + <para> + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + </para> + + <para> + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + </para> + + <para> + d) If a facility in the modified Library refers to a function or + a table of data to be supplied by an application program that + uses the facility, other than as an argument passed when the + facility is invoked, then you must make a good faith effort to + ensure that, in the event an application does not supply such + function or table, the facility still operates, and performs + whatever part of its purpose remains meaningful. + </para> + + <para> + (For example, a function in a library to compute square roots + has a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function + must be optional: if the application does not supply it, the + square root function must still compute square roots.) + </para> + + <para> + These requirements apply to the modified work as a whole. If + identifiable sections of that work are not derived from the + Library, and can be reasonably considered independent and + separate works in themselves, then this License, and its terms, + do not apply to those sections when you distribute them as + separate works. But when you distribute the same sections as + part of a whole which is a work based on the Library, the + distribution of the whole must be on the terms of this License, + whose permissions for other licensees extend to the entire + whole, and thus to each and every part regardless of who wrote + it. + </para> + + <para> + Thus, it is not the intent of this section to claim rights or + contest your rights to work written entirely by you; rather, the + intent is to exercise the right to control the distribution of + derivative or collective works based on the Library. + </para> + + <para> + In addition, mere aggregation of another work not based on the + Library with the Library (or with a work based on the Library) + on a volume of a storage or distribution medium does not bring + the other work under the scope of this License. + </para> + + <para> + 3. You may opt to apply the terms of the ordinary GNU General + Public License instead of this License to a given copy of the + Library. To do this, you must alter all the notices that refer + to this License, so that they refer to the ordinary GNU General + Public License, version 2, instead of to this License. (If a + newer version than version 2 of the ordinary GNU General Public + License has appeared, then you can specify that version instead + if you wish.) Do not make any other change in these notices. + </para> + + <para> + Once this change is made in a given copy, it is irreversible for + that copy, so the ordinary GNU General Public License applies to + all subsequent copies and derivative works made from that copy. + </para> + + <para> + This option is useful when you wish to copy part of the code of + the Library into a program that is not a library. + </para> + + <para> + 4. You may copy and distribute the Library (or a portion or + derivative of it, under Section 2) in object code or executable + form under the terms of Sections 1 and 2 above provided that you + accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of + Sections 1 and 2 above on a medium customarily used for software + interchange. + </para> + + <para> + If distribution of object code is made by offering access to + copy from a designated place, then offering equivalent access to + copy the source code from the same place satisfies the + requirement to distribute the source code, even though third + parties are not compelled to copy the source along with the + object code. + </para> + + <para> + 5. A program that contains no derivative of any portion of the + Library, but is designed to work with the Library by being + compiled or linked with it, is called a "work that uses the + Library". Such a work, in isolation, is not a derivative work of + the Library, and therefore falls outside the scope of this + License. + </para> + + <para> + However, linking a "work that uses the Library" with the Library + creates an executable that is a derivative of the Library + (because it contains portions of the Library), rather than a + "work that uses the library". The executable is therefore + covered by this License. Section 6 states terms for distribution + of such executables. + </para> + + <para> + When a "work that uses the Library" uses material from a header + file that is part of the Library, the object code for the work + may be a derivative work of the Library even though the source + code is not. Whether this is true is especially significant if + the work can be linked without the Library, or if the work is + itself a library. The threshold for this to be true is not + precisely defined by law. + </para> + + <para> + If such an object file uses only numerical parameters, data + structure layouts and accessors, and small macros and small + inline functions (ten lines or less in length), then the use of + the object file is unrestricted, regardless of whether it is + legally a derivative work. (Executables containing this object + code plus portions of the Library will still fall under Section + 6.) Otherwise, if the work is a derivative of the Library, you + may distribute the object code for the work under the terms of + Section 6. Any executables containing that work also fall under + Section 6, whether or not they are linked directly with the + Library itself. + </para> + + <para> + 6. As an exception to the Sections above, you may also combine + or link a "work that uses the Library" with the Library to + produce a work containing portions of the Library, and + distribute that work under terms of your choice, provided that + the terms permit modification of the work for the customer's own + use and reverse engineering for debugging such modifications. + </para> + + <para> + You must give prominent notice with each copy of the work that + the Library is used in it and that the Library and its use are + covered by this License. You must supply a copy of this License. + If the work during execution displays copyright notices, you + must include the copyright notice for the Library among them, as + well as a reference directing the user to the copy of this + License. Also, you must do one of these things: + </para> + + <para> + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable + linked with the Library, with the complete machine-readable + "work that uses the Library", as object code and/or source code, + so that the user can modify the Library and then relink to + produce a modified executable containing the modified Library. + (It is understood that the user who changes the contents of + definitions files in the Library will not necessarily be able to + recompile the application to use the modified definitions.) + </para> + + <para> + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer + system, rather than copying library functions into the + executable, and (2) will operate properly with a modified + version of the library, if the user installs one, as long as the + modified version is interface-compatible with the version that + the work was made with. + </para> + + <para> + c) Accompany the work with a written offer, valid for at least + three years, to give the same user the materials specified in + Subsection 6a, above, for a charge no more than the cost of + performing this distribution. + </para> + + <para> + d) If distribution of the work is made by offering access to + copy from a designated place, offer equivalent access to copy + the above specified materials from the same place. + </para> + + <para> + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + </para> + + <para> + For an executable, the required form of the "work that uses the + Library" must include any data and utility programs needed for + reproducing the executable from it. However, as a special + exception, the materials to be distributed need not include + anything that is normally distributed (in either source or + binary form) with the major components (compiler, kernel, and so + on) of the operating system on which the executable runs, unless + that component itself accompanies the executable. + </para> + + <para> + It may happen that this requirement contradicts the license + restrictions of other proprietary libraries that do not normally + accompany the operating system. Such a contradiction means you + cannot use both them and the Library together in an executable + that you distribute. + </para> + + <para> + 7. You may place library facilities that are a work based on the + Library side-by-side in a single library together with other + library facilities not covered by this License, and distribute + such a combined library, provided that the separate distribution + of the work based on the Library and of the other library + facilities is otherwise permitted, and provided that you do + these two things: + </para> + + <para> + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + </para> + + <para> + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + </para> + + <para> + 8. You may not copy, modify, sublicense, link with, or + distribute the Library except as expressly provided under this + License. Any attempt otherwise to copy, modify, sublicense, link + with, or distribute the Library is void, and will automatically + terminate your rights under this License.

The notice must be conspicuously + included in any notice in an Executable version, related + documentation or collateral in which You describe recipients' + rights relating to the Covered Code. You may distribute the + Executable version of Covered Code or ownership rights under a + license of Your choice, which may contain terms different from + this License, provided that You are in compliance with the terms + of this License and that the license for the Executable version + does not attempt to limit or alter the recipient's rights in the + Source Code version from the rights set forth in this License. + If You distribute the Executable version under a different + license You must make it absolutely clear that any terms which + differ from this License are offered by You alone, not by the + Initial Developer or any Contributor.

Problems are + usually not host OS specific, because most of the + &product-name; code base is shared across all supported + platforms, but especially in the areas of networking and USB + support, there are significant differences between host + platforms. Some GUI related issues are also host specific. + </para> + </listitem> + + <listitem> + <para> + Is the problem specific to certain host hardware? This + category of issues is typically related to the host CPU. + Because of significant differences between VT-x and AMD-V, + problems may be specific to one or the other technology. The + exact CPU model may also make a difference because different + CPUs support different features, which may affect certain + aspects of guest CPU operation. + </para> + </listitem> + + <listitem> + <para> + Is the problem specific to guest SMP? That is, is it related + to the number of virtual CPUs (VCPUs) in the guest? Using + more than one CPU usually significantly affects the internal + operation of a guest OS. + </para> + </listitem> + + <listitem> + <para> + Is the problem specific to the Guest Additions? In some + cases, this is obvious, such as a shared folders problem. In + other cases such as display problems, it may be less + obvious. If the problem is Guest Additions specific, is it + also specific to a certain version of the Guest Additions? + </para> + </listitem> + + <listitem> + <para> + Is the problem specific to a certain environment? Some + problems are related to a particular environment external to + the VM. This usually involves network setup. Certain + configurations of external servers such as DHCP or PXE may + expose problems which do not occur with other, similar + servers. + </para> + </listitem> + + <listitem> + <para> + Is the problem a regression?
