[TriLUG] Fighting Ubuntu Desktop + KVM + network bridging

[Jason Herr]

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.

Thanks,
J
