One property of virtual machine monitors (VMMs) like
|
|
<ph conkeyref="vbox-conkeyref-phrases/product-name"/> is to encapsulate a guest by executing it in a
|
|
protected environment, a virtual machine, running as a user
|
|
process on the host operating system. The guest cannot
|
|
communicate directly with the hardware or other computers but
|
|
only through the VMM. The VMM provides emulated physical
|
|
resources and devices to the guest which are accessed by the
|
|
guest operating system to perform the required tasks. The VM
|
|
settings control the resources provided to the guest, for
|
|
example the amount of guest memory or the number of guest
|
|
processors and the enabled features for that guest. For example
|
|
remote control, certain screen settings and others. See
