BIOS.ProcSettings.ProcVirtualization (Read or Write)
Description
When set to Enabled, the BIOS will enable processor Virtualization features and provide the virtualization
support to the Operating System (OS) through the DMAR table. In general, only virtualized environments
such as VMware(r) ESX(tm), Microsoft Hyper-V(r), Red Hat(r) KVM, and other virtualized operating
systems will take advantage of these features. Disabling this feature is not known to significantly alter the
performance or power characteristics of the system, so leaving this option Enabled is advised for most
cases.
