> A few months ago, in xen mailing list I remember some guys reported: when using PEG card (turning off integrated Gfx) on Q35, VT-d cannot work. It's the bios issue. I suspect it's not fixed yet. So I suggest you to use IGD instead of PEG.
I would, but if i do not select PEG in bios, lspci did not show the
PEG card.
