Change IP Address of Ovirt Engine
We have an operational ovirt cluster where all nodes on 1 IP Network, and the oVirt Engine is on another IP Network and are wanting to change IP Address of the host of the ovirt engine so that it is on the same network as the nodes that are managed. I have not been able to find a definative answer, but since I are NOT changing the name of the ovirt engine host, from what I have read it seems that all I will need to do is alter the IP Address in the DNS of the hostname for the ovirt engine host (apart from plumbing and address on the new network into the ovrit engine host of course). Is this correct, or is there some configuration file on either the engine host or the nodes that needs to be updated to reflect the new IP Address of the engine host ? -- Regards, Phil Gersekowski IT Director http://www.aspedia.net <http://www.aspedia.net/> | philg@aspedia.net <mailto:Phil%20Gersekowski%20%3Cphilg@aspedia.net%3E> ------------------------------------------------------------------------ Aspedia <http://aspedia.net/> Phone: *1800 677 656* Mobile: *0447 546 890* Suite 1, 1 Clunies Ross Court, Eight Mile Plains QLD 4113 | Map <https://www.google.com/url?sa=D&oi=plus&q=https://maps.google.com.au/maps?expflags%3Denable_star_based_justifications:true%26ie%3DUTF8%26cid%3D15512870260820148947%26q%3DAspedia%26iwloc%3DA%26gl%3DAU%26hl%3Den> ------------------------------------------------------------------------ This message and any files transmitted with it are confidential and should be read only by those persons to whom it is addressed.

Hi, if you configured everything using FQDN only and you're changing IP preserving FQDN everything should continue working. BTW, I suggest to wait for someone from network team to confirm

I have not been able to find a definative answer, but since I are NOT changing the name of the ovirt engine host, from what I have read it seems that all I will need to do is alter the IP Address in the DNS of the hostname for the ovirt engine host (apart from plumbing and address on the new network into the ovrit engine host of course).
Is this correct, or is there some configuration file on either the engine host or the nodes that needs to be updated to reflect the new IP Address of the engine host ?
Hi, if you configured everything using FQDN only and you're changing IP preserving FQDN everything should continue working. BTW, I suggest to wait for someone from network team to confirm
Yes, if you have used the fqdn everywhere, updating the DNS to a new IP address sohuld not matter much to oVirt. Do note that we use long-living TCP connections, so they would break on the transition. It is safer to take Engine down before making the change, so not operation is broken mid-way.
