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
