Take a look at http://wiki.xensource.com/xenwiki/VTdHowTo
Two things in particular about PCI passthrough:
- Only devices with FLR capabilities are supported.
- Some motherboards are buggy. They advertised that they support Vt-d
but do not correctly handle it (those with a broken ACPI DMAR table)
I think lspci -vv will tell you if the device supports FLR. It will show
'FLReset+' I believe.
