Hi,

I was able to successful live migrate vms across two compute nodes. I used the details indicated in the below link http://kimizhang.wordpress.com/2013/08/26/openstack-vm-live-migration/ (http://kimizhang.wordpress.com/2013/0...)

Migration of VM seem to use management network, is this expected? If not how do we initiate vm migration through data plane. Please advice.

Regards,

Hello,

as far as I know the destination host is specified by the hostname instead of ip address directly. The actual ip address is resolved as described in /etc/host file - changing it here and restarting networking service should do the trick.

e.g. let's assume we have 2 network interfaces (eth0 with 10.0.0.x assigned and eth1 with 192.168.0.x) on each host host-x. Records in /etc/hosts look like this: 192.168.0.x node-x node-x.domain.tld That means all traffic denoted by the hostname node-x will go through eth1 since it has assigned the ip address within the same subnetwork. Change this record to: 10.0.0.x node-x node-x.domain.tld and your traffic will go through eth0.

Note: try to keep your /etc/host records consistent across all your nodes to avoid confusion.

Hope it helps. Cheers!
