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

Hi,

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?
