How to assign devices with VT-d in KVM - KVM

VT-d support In order to assign devices in KVM, you'll need a system which supports VT-d, not to be confused with the VT-x support of your CPU. VT-d needs to be supported by both your motherboard chipset and your CPU. If you are in doubt whether your motherboard or CPU supports VT-d, the Xen VT-d wiki has some information about VT-d enabled chipsets, motherboards, and CPUs: http://wiki.xenproject.
