I think that you need to:
1. Put in maintenance
2. Unregister
3. Remove host
4. Change IP
5. Add host to oVirt again

Please, someone more experienced to share any thoughts.

Hello Guys

Have 8 host with Ovirt 4.1 and need change the IP to all node.

There is a procedure to make the change of IP, I have searched for information but I can not find a process to perform.

Someone could help me to know how I can change the IP in the nodes, I know that I must put the nodes in maintenance, but I do not know if I should change the manager first, add an additional IP and then add the nodes, etc.

Thanks for the help

Sebastian
