Hi,

I am trying to make the vt-d and pci pass-through work and I have some problems. I just try to give a NIC to an HVM guest.

When I create the vm the hypervisor goes to an infinite loop,
it displays in loop the message enclosed (console_on_xm_create).

I use xen x86_64, debian etch dom0 with linux-2.6.18.8-xen 32.
The hvm guest is a debian etch 64.

Cheers,
