[Xen-users] 32bit on 64-bit causes guest Kernel oops

["Nathan Widmyer" <lighthousej@xxxxxxxxx>]

I'm trying to install a RHEL 5 32-bit guest on a F7 64-bit host.
It seems to crash as its booting anaconda.

Versions:
Compiled against library: libvir 0.3.1
Using library: libvir 0.3.1
Using API: Xen 
3.0.1
Running hypervisor: Xen 3.1.0

Is the version mismatch between the API and hypervisor versions a problem?

Serial Console crash:
