RE: [Xen-users] HVM and Intel VT processors

["Tait Clarridge" <Tait.Clarridge@xxxxxxxxxxxx>]

Hello,

The GPLPV drivers provide paravirtualized drivers for networking, disk and 
others that improve that performance in HVM domains. The regular HVM domains 
use the default qemu-dm for devices. The CPU's VT instructions don't handle 
device drivers :)

I wish I could tell you more, but the without the VT enabled CPUs you wouldn't 
be able to run a Windows domU.

Best,

Tait

Hello!
I'm wondering about installing windows server on xen-hvm, I have VT
enabled cpu's. Do I need install GPLPW drivers to get better
performance? Or the cpu's will do that work? As stands here:
http://www.virtuatopia.com/index.php/An_Overview_of_Virtualization_Techniques#Hardware_Virtualization
then VT enabled cpu's will enshure. that unmodified guest virtual
machines will run without the overheads. Is this true?
