Hi All: I just has a case, I need to change the oVirt host and engine IP address due to data center decommission I checked in the hosted-engine host there are some files I could change ; in ovirt-hosted-engine/hosted-engine.conf ca_subject="O=simple.com, CN=1.2.3.4" gateway=1.2.3.254 and of course I need to change the ovirtmgmt interface IP too, I think just change the above line could do the tick, but where could I change the other host IP in the cluster ? I think I have to be lost all the host as once changed the hosted-engine host IP as it is in diff. sub net. Does there any command line tools could do that or someone has such experience could share?

Hi All: To be honest I do not see any config file in the host node /etc/ovirt-node inside, so even I put in the global maintenance mode I still don't know how to change the host to the new IP address.

Hey Paul, if you are using oVirt Node (btw what version are you using?), then there are a couple of files, there is /etc/default/ovirt and the well known ifcfg files: /etc/sysconfig/netwprk-scripts/ifcfg-* And some other paths which are handled by vdsm. And vdsm is actually managing the network configuration when a Node is registered, that means, it can be that any changes to the configuration files get overwritten by vdsm again. Maybe Toni can say something about this. And I am also not sure if Engine will still recognize a Node, when you change the IP of the Node, without letting the Engine know about that. Sandro, do you know how you can tell Engine that the IP of a Node changed?
