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.

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 ?

guess not

regards
