<p>yes i already tried that and works. but i was thinking in a schema where al nodes have the network and scheduler services installed and i can switch them via custom heartbeat resource. Everything worked but that. Maybe i can update the contoller hostname on switch. </p>
<p>using a vip like dns entry and pointing that on the nova conf will change that behavior or.the controller will still resolving via hostname ? </p>
<p>guess not</p>
<p>regards</p>
