That was the ticket. Because I was running a static IP, NetworkManager
kept trying to load its configuration into the system too. By disabling
the NIC in NetworkManager, I was able to get it going all going.
Also, I found that virsh was much more useful than the VirtManager in
Ubuntu. Also, I ended up having to run virsh under sudo to allow the
vnet device to enter promiscuous mode...
I swear I remember seeing the VirtManager in FC and RHEL with more
features, but it was a demo and it's been a while.
