HVM guest uses PCI
bus provided by QEMU. The functionality in QEMU is complete for PCI
passthrough support most devices. Additional patch is needed for
graphics device passthrough.

Dom0 with pciback + DomU with pcifront. pcifront grabs
device during DomU boot and vendor driver then loads against passthrough device
and works great!
In the same scenario with HVM DomU, is pcifront needed or
does qemu provide the PCI Bus ?
Both Linux and Win32 hvm fail to load the vendor driver
against the PCI device. Is this a problem with qemu or is further support
needed in hvm domU for PCI passthrough?
Thanks,
Tim
