Hello, I installed an ovirt node and its hosted engine in a lab. After several difficulties to install the engine (I don't know why, I didn't have any problem in the past), I would like to change IPs of both to put them on another vlan. How can I do that without break anything ? My main fear is that the data domain used by the hosted engine use the IP of the node rather than its FQDN. I change other data domains paths, but don't find how to change this one, 'cause I can't modify it, and I can't detach / delete it to recreate another one. I didn't find how to move the engine on another data domain using the node's FQDN in its path. For now, I don't use DNS, I just updated /etc/hosts defs on both servers. If someone could help me, telling me step by step how to change IPs on each element in good order, I would be grateful. Thank you. Cheers, Stephane
