In the coming oVirt 3.3 we should be able to handle this by separating the migration network, and then use- http://www.ovirt.org/Features/Network_QoS Doron

Hi Joop. What is your actual problem here ? I have seperated nics for: - Management - VM (Internal/LAN) - VM (Outside/WAN) - Storage Or are you putting everything over one pipe ? Cheers, Matt 2013/7/14 Joop <jvdwege(a)xs4all.nl&gt;
