+VirtualBox Test eXecution Service
+=================================
+
+This readme briefly describes how to install the Test eXecution Service (TXS)
+on the various systems.
+
+There are currently two transport options for the TXS:
+
+ - The default is to use it in TCP server mode, i.e. the test script needs
+ to know the guest's IP and therefore requires guest additions to be
+ installed as well. (Please use the latest stable additions compatible with
+ the VBox host versions you intend to test.)
+
+ - The alternative is for NATted setups where TXS will act like a TCP client
+ and try connect to the test script on the host. Since this require that
+ TXS knows which IP to connect to, it's only really possible in a NATted
+ setup where we know the host IP is 10.0.2.2.
+
+Since r85596 TXS operates in both modes by default so the nat version of
+the init scripts is not required anymore. Instead the other type can be installed
+for both cases.
+
+Linux Installation
+------------------
+
+1. mkdir -p /opt/validationkit
+2. scp/download VBoxValidationKit*.zip there.
+3. unzip VBoxValidationKit*.zip
+4. chmod -R u+w,a+x /opt/validationkit/ && chown -R root.root /opt/
+5. cd /etc/init.d/
+
+6 a) For init.rc distros:
+ Link up the right init script (see connection type above):
+ nat) ln -s ../../opt/validationkit/linux/vboxtxs-nat ./vboxtxs
+ other) ln -s ../../opt/validationkit/linux/vboxtxs ./vboxtxs
+6 b) Add vboxtxs to runlevels 2, 3, 5 and any other that makes sense
+ on the distro. There is usually some command for doing this, e.g.
+ ```update-rc.d vboxtxs defaults && update-rc.d vboxtxs enable``` (Debian-based)
+ or
+ ```chkconfig --add vboxtxs``` (OL/RHEL)
+
+ ... or ...
+
+7 a) For systemd distros: Link/copy up the vboxtxs.system to [/usr]/lib/systemd/, e.g.
+ cp /opt/validationkit/linux/vboxtxs.service /etc/systemd/system
+ b) Enable the vboxtxs service via:
+ systemctl enable vboxtxs
+
+ For all distros again:
+
+8a. Check the CD-ROM location (--cdrom <path>) in vboxtxs and fix it so it's correct, make sure
+ to update in svn as well.
+8b. Optional: If no suitable CD-ROM location is available on the guest yet, do a:
+ mkdir -p /media/cdrom; vi /etc/fstab
+ and enter this in /etc/fstab:
+ /dev/sr0<tab>/media/cdrom<tab>udf,iso9660<tab>user,noauto,exec,utf8<tab>0<tab>0
+8c. Optional: If SELinux denies execution of TXS, make sure to allow this, based on
+ how the distribution handles SELinux exceptions. Often there even is a GUI for that
+ (e.g. Oracle Linux 8+).
+9. Make sure that the package sources are still valid and up to date (apt / yum / ++)
+10. reboot / done.
+11. Do test.
+
+
+OS/2 Installation
+--------------------
+
+1. Start an "OS/2 Window" ("OS/2 System" -> "Command Prompts")
+2. md C:\Apps
+3. cd C:\Apps
+4. Mount the validationkit iso.
+5. copy D:\os2\x86\* C:\Apps
+5. copy D:\os2\x86\libc*.dll C:\OS2\DLL\
+6. Open C:\startup.cmd in an editor (tedit.exe for instance or e.exe).
+7. Add the line "start /C C:\Apps\TestExecService.exe --foreground" at the top of the file.
+8. reboot / done
+9. Do test.
+
+
+Solaris Installation
+--------------------
+
+1. Start the guest and open a root console.
+2. mkdir -p /opt/VBoxTest
+3. cd /opt/VBoxTest
+4. scp/download VBoxValidationKit*.zip there.
+5. unzip VBoxValidationKit*.zip
+6. chmod -R u+w,a+x /opt/VBoxTest/
+7. Import the right service setup depending on the Solaris version:
+ <= 10u9) /usr/sbin/svccfg import /opt/VBoxTest/validationkit/solaris/vboxtxs-sol10.xml
+ >= 11.0) /usr/sbin/svccfg import /opt/VBoxTest/validationkit/solaris/vboxtxs.xml
+8. /usr/sbin/svcadm enable svc:/system/virtualbox/vboxtxs
+9. reboot / done.
+
+To remove the service before repeating steps 7 & 8:
+1. /usr/sbin/svcadm disable -s svc:/system/virtualbox/vboxtxs:default
+2. /usr/sbin/svccfg delete svc:/system/virtualbox/vboxtxs:default
+
+Note. To configure dhcp for more a new interface the files
+/etc/hostname.<if#X> and /etc/dhcp.<ifnm#> have to exist. If you want the VM
+to work with any network card you throw at it, create /etc/*.pcn[01] and
+/etc/*.e1000g[012] as Solaris will remember it has seen the other variants
+before and use a different instance number (or something to that effect).
+
+
+Windows Installation
+--------------------
+
+1. Log on as Administrator.
+2. Make sure you have set a secure password, which you'll need in step 9.
+3. Start CMD.EXE or equivalent.
+4. md C:\Apps
+5. cd C:\Apps
+6. Mount the validationkit iso.
+7. copy D:\win\* C:\Apps
+8. copy D:\win\<x86 or amd64>\* C:\Apps
+9. Put the password from step 2 into the right service setup (see connection
+ type above) and import it into the registry:
+ nat) start C:\Apps\vboxtxs-nat.reg
+ other) start C:\Apps\vboxtxs.reg
+10. Make sure that the CD-ROM location is assigned to D: (via "Disk Management").
+11. reboot / done
+12. Do test.
+
+NT 3.1 and 3.x tricks:
+- Make sure the file system is NTFS. Observed issues converting 2GB partitions,
+ more success with smaller.
+- For NT3.1 PCNET drivers can be found on the net. No DHCP, so NAT only with
+ IP 10.0.2.15, 10.0.2.2 as gateway, and 10.0.2.3 as DNS with --natdnsproxy1 on.
+- On NT3.1 you need to add SystemDrive=C: to the environment.
+- Need to perform registry edits manually.
+- Use startup folder instead of non-exising Windows/Run key.
+
+
+Testing the setup
+-----------------
+
+1. Make sure the validationkit.iso is inserted.
+2. Boot / reboot the guest.
+3. Depending on the TXS transport options:
+ nat) python testdriver/tst-txsclient.py --reversed-setup
+ other) python testdriver/tst-txsclient.py --hostname <guest-ip>

+VirtualBox Test eXecution Service
+=================================
+
+This readme briefly describes how to install the Test eXecution Service (TXS)
+for nested hardware-virtualization smoke testing on the various systems.
+
+The basic idea is to execute one smoke test within the VM and then launch
+the regular TXS service in the VM to report success or failure to the host.
+
+Linux Installation
+------------------
+
+1. scp/download latest release build of VirtualBox and install it in the VM.
+2. scp/download the required smoke test VDI from remote test-resource to
+ /home/vbox/testrsrc/3.0/tcp/win2k3ent-acpi.vdi
+3. cd /root
+3. scp/download VBoxValidationKit*.zip there.
+5. unzip VBoxValidationKit*.zip
+6. chmod -R u+w,a+x /opt/validationkit/
+7a. Gnome: Copy /opt/validationkit/linux/vboxtxs-runvm.desktop to /etc/xdg/autostart
+7b. KDE/Others: TODO: Document other desktop managers
+8. Add the vbox user to sudo group using:
+ sudo usermod -a -G sudo vbox
+9. Ensure no password is required for vbox when using sudo:
+ sudo echo "vbox ALL=(ALL:ALL) NOPASSWD: ALL" > /etc/sudoers.d/username
+10. Check the cdrom location and /dev/kmsg equivalent of your linux distro
+ in /opt/validationkit/linux/vboxtxs-runvm and fix it so it's correct
+11. Reboot / done.
+
+TODO: Document other OSes as we add them.
+
+Note: vboxtxs-runvm uses a GUI session to launch the nested-VM for better
+visibility when troubleshooting the nested smoke test.
+
+If this causes problems try troubleshooting the XAUTHORITY and DISPLAY
+environment variables in vboxtxs-runvm.service. It might differ depending
+on the display manager of the particular linux distro.
+
+
+
+Testing the setup
+-----------------
+
+1. Make sure the validationkit.iso is inserted.
+2. Boot / reboot the guest.
+3. To test the connection - Depending on the TXS transport options:
+ nat) python testdriver/tst-txsclient.py --reversed-setup
+ other) python testdriver/tst-txsclient.py --hostname <guest-ip>
+4. To test the smoke test:
+ python tests/smoketests/tdSmokeTest1.py -v -v -d --vbox-session-type gui --test-vms <guest-name>

+ *
+ * This self-test does the following:
+ * - 1. Creates a separate thread for the guest side VKAT and connects to the ATS instance on
+ * the host side at port 6052 (ATS_TCP_DEF_BIND_PORT_HOST).
+ * - 2. Uses the Validation Kit audio backend, which in turn creates an ATS instance
+ * listening at port 6062 (ATS_TCP_DEF_BIND_PORT_VALKIT).
+ * - 3. Uses the host test environment which creates an ATS instance
+ * listening at port 6052 (ATS_TCP_DEF_BIND_PORT_HOST).
+ * - 4. Executes a complete test run locally (e.g. without any guest (VM) involved).
