Intel Virtualization Technology must be enabled in F10 Setup before a VA can be launched. VT is dis-
abled by default in F10 Setup.
A VA can be installed with VT enabled or disabled, although some VA installers may warn users that VT
is disabled during installation. If VT is disabled during installation, enter F10 Setup and enable VT after
the installation is complete.
There are two kinds of Intel Virtualization Technology: VTx and VTd.
Intel Virtualization Technology for IA-32 processors (VTx) deals with virtualization at the processor level.
This must be enabled for a VA to function.
Virtualization Technology Directed I/O (VTd) is an extension of VTx and deals with virtualization at the
chipset level. VTd provides the capability to control DMA accesses and direct them to specific domains
which are regions in physical memory.
All Core 2 Duo processors support VTx. More advanced versions of Core 2 Duo also support VTd in addi-
tion to VTx. Depending on which VT is supported by the processor, one or both options may appear in
F10 Setup.
