Re: [Xen-users] use PCI VGA card on domU, and questions about USB


All the AMD CPUs (I guess except for the lower end Semprons, but I guess those also apply) from the last (at least 4-5 years) have virtualization caps. It is shown as "svm" in the CPU flags:

Offcourse, the BIOS must support it too. And I guess you need to either buy another mobo (see Gigabyte or Asus), or hammer your mobo producer to release a BIOS to support it. What is your mobo anyways?

It's almost latest processor available. It was bleeding edge when i
bought it. Bigger AMD are not compatible with AM3.
Hmmm...Google searches don't turn up much for that CPU supporting VTd (or 
whatever AMD calls I/O virtualization).  You might check out the specs on the 
AMD site for that processor and see if they have anything.  I use Intel 
processors, and I know Intel has a place on the specs for each of their 
processors that tells about I/O virtualizaiton.
