Thomas,

I had to enable msi, since I was getting errors when the interfaces were brought up as suggested below:

http://www.nabble.com/Xen-3.3.0-PCI-passthrough-with-pciback.hide-td20835971.html

I could certainly try with the 2.6.26-XEN-Kernel.

Could you please explain how would I go about using a different kernel than the one the Xen build downloads using hg?

I am installing Xen 3.3.0 from sources.
