Hi James-

AFAIK, the Intel G33 does not support the VT-d extensions forVirtualization.

Hi,

I'm having some problems assigning a PCI device to an OpenBSD HVM.  The
HVM will boot without the pci = line in the configuration but as soon as
it is added I get:

# xm create hvm_obsd
Using config file "/etc/xen/hvm_obsd".
Error: Fail to assign device(1:0.0): maybe VT-d is not enabled, or the
device is not exist, or it has already been assigned to other domain

My system is running Gentoo using the 2.6.21-xen kernel and Xen 3.2.1.
I believe that the hardware I am using should support VT-d - a Gigabyte
GA-G33M-S2 (i.e. Intel G33 chipset) and a Core 2 Duo E8200 processor.  I
am also confident that the PCI device has been seized by the pciback
driver:
