Hmm. So on the interface issue, what networks do you have defined, and
how have you mapped the interfaces on the host to them? We shouldn't
ever be trying to bridge the admin NIC, so if that's eth0 that could be
the problem.

On the other hand, it could be as simple as rebooting the node, which
you have to do once you map networks to it (and we have failed to
document that).

I'm not aware of any issues with the node using KVM. Is VT definitely
turned on in the bios?

Hope this helps,
