Hi there..
I've got the folowing error while trying to assign the video card from
Dom0 to DomU

Using config file "/etc/xen/winkk".
Error: failed to assign device: maybe the platform doesn't support VT-d,
or VT-d isn't enabled properly?

What Am I missing? obviously I've got VT support enable, cuz I was able
to create the Windows DomU.

Config file
pci=[ '01:05.0' ]

lspci
01:05.0 VGA compatible controller: ATI Technologies Inc Device 9710

grub config

module /boot/vmlinuz-2.6.31.13 ro root=/dev/sda1 xen-pciback.hide=(01:05.0)

Anyway xm pci-list-assignable-devices show nothing, what's wrong?


Thanks is advance
Regards

VT-d support (PCI passthrough) is a subset of VT-x support. Not all chipsets support VT-d nor is it required for full-virtualization of guests. (i.e. Windows)

Cheers,
Daniel
