Support hosting fully virtualized guest machines using hardware
|
|
virtualization extensions. You will need a fairly recent
|
|
processor equipped with virtualization extensions. You will also
|
|
need to select one or more of the processor modules.
|
|
|
|
This module provides access to the hardware capabilities through
|
|
a character device node named /dev/kvm.

|
|
Intel GVT-g is a technology that provides mediated device
|
|
passthrough for Intel GPUs (Broadwell and newer). It can
|
|
be used to virtualize the GPU for multiple guest virtual
|
|
machines, effectively providing near-native graphics performance
|
|
in the virtual machine and still letting your host use the
|
|
virtualized GPU normally.
|
|
|
|
Choose this option if you want to enable Intel GVT-g graphics
|
|
virtualization technology host support with integrated graphics.
|
|
With GVT-g, it's possible to have one integrated graphics
|
|
device shared by multiple VMs under different hypervisors.
|
|
|
|
Note that at least one hypervisor like Xen or KVM is required for
|
|
this driver to work, and it only supports newer device from
|
|
Broadwell+. For further information and setup guide, you can
|
|
visit: http://01.org/igvt-g.
|
|
|
|
Now it's just a stub to support the modifications of i915 for
|
|
GVT device model. It requires at least one MPT modules for Xen/KVM
|
|
and other components of GVT device model to work. Use it under
|
|
you own risk.
