[Xen-devel] RE: pciback+front needed for hvm ?
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.

Subject: [Xen-devel] pciback+front needed for hvm ?
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
