Hi! What I found out the hard way under the Xen hypervisor is that the GPU you are passing through must not be the primary GPU of the system. Otherwise, you get memory corruption as soon as something appears on the console. If not sooner :-). Test if your motherboards are capable of running on the integrated VGA even if some other graphics card is connected. Or blacklist it for the kernel.
