| 8 | One property of virtual machine monitors (VMMs) like
|
|---|
| 9 | <ph conkeyref="vbox-conkeyref-phrases/product-name"/> is to encapsulate a guest by executing it in a
|
|---|
| 10 | protected environment, a virtual machine, running as a user
|
|---|
| 11 | process on the host operating system. The guest cannot
|
|---|
| 12 | communicate directly with the hardware or other computers but
|
|---|
| 13 | only through the VMM. The VMM provides emulated physical
|
|---|
| 14 | resources and devices to the guest which are accessed by the
|
|---|
| 15 | guest operating system to perform the required tasks. The VM
|
|---|
| 16 | settings control the resources provided to the guest, for
|
|---|
| 17 | example the amount of guest memory or the number of guest
|
|---|
| 18 | processors and the enabled features for that guest. For example
|
|---|
| 19 | remote control, certain screen settings and others. See
