Re: [Xen-devel] 82576 VF passthrough

Hi Greg,
I am using Vt-d machine. Sorry for the confusion.
My Hardware is HP  dc7800p Chipset: Q35, with Intel Core 2 Duo E8400 processor. NIC Card  is 82576 E1G42ET (dual port RJ-45 copper).

Is VF passthrough can be done only to HVM guest? Is VF passthrough to paravirtal guest is supported?

Regards,
-Satish

You can't run SR-IOV VF devices in VM guests on a non Vt-d machine.  VT-d is required for VF passthrough to a guest.
