It's a flat network on the compute node, I created a vlan directly on  
the compute node to avoid sending all the traffic to the  
control/network node for instances that are supposed to be in a  
productive environment. And until a couple of days ago, maybe two  
weeks, this doesn't work as it used to. I have been testing all the  
time while instances were running in that network, but without impact  
on their connectivity. Now it seems that several services have some  
kind of impact on neutron on the compute nodes. I just figured out  
that restarting libvirtd also leads to an interruption.
