Well, I really love oVirt, but I don't know.. All the solutions mentioned
here are complicated and or dangerous. Including hosted ha engine that
fails while deploying(for me). I think that test the backup for recovery is
very important and need to be done on a regular basis, What good is a
backup if you cannot restore?? I worked for a whole night trying to
recover the failed engine...recovery from backup was very painful. does
anyone here have a solution for testing backups (not in crises mode)?

I'm still sort of new to ovirt, but I went through a similar
things. I
had my original engine fail and had to recover, so here is my "oVirt HA
plan"
1. I do NOT use hosted ovirt, I had issues getting it deployed correctly,
and that doesn't help if they engine VM itself has issues. My engine is
hosted on a completely separated 2-node hyper-converged Hyper-V Cluster.
Unless you have a cluster larger than 3 hosts, I really don't think hosted
ovirt is a good idea, it would make more sense to just load ovirt on
another PC by itself.
2. I plan on loading another copy of ovirt in a "cold storage"
configuration. Where it will be loaded on centos, and configured as close
as I can without adding in any hosts. I'll probably keep it turned off and
try to updated it once a month or so.
3. If I have another oVirt failure, I know to log in, put the storage
domains into maintenance mode if possible, and copy out any needed config
items i may have missed. I will the shut it off and delete it. I then
will reboot all the hosts one at a time to clear out any sanlock issues,
then add the hosts to the new copy of ovirt and import the storage. I
estimate that process to take around 2-4hrs.
