Open Stack

Sending back to Openstack list since other people might help you better 
than me, anyway:

Can you post result from:

$ virsh net-dumpxml default

I'm not sure about this, but It seems host is trying wrong bridge when 
connecting your vms, I had similar problem installing from source, since 
I was trying old instructions and openstack networks default had 
changed. Script you are using might be not updated too.
