Description
When enabled, a hypervisor or operating system
supporting this option can use hardware
capabilities provided by Intel VT. Some hypervisors
require that you enable Intel VT. You can leave this
set to enabled even if you are not using a
hypervisor or an operating system that uses this
option.
If enabled, a hypervisor or operating system
supporting this option can use hardware
capabilities provided by Intel VT for Directed I/O.
You can leave this set to enabled even if you are
not using a hypervisor or an operating system that
uses this option.
If enabled, SR-IOV support enables a hypervisor to
create virtual instances of a PCI-express device,
potentially increasing performance. If enabled, the
BIOS allocates additional resources to PCI-express
devices. You can leave this option set to enabled
even if you are not using a hypervisor.
