Hi All,
Is there a documentation on creating Ovirt-Manager in HA or is it possible to make the
manager to run in HA environment. Since it seems to be a single point of failure..!!
Thanks

Hello,
the solution is to use hosted-engine. This implements automatic HA for
the engine vm.

As the other response alluded to - proper HA ovirt engine is a hosted VM
ovirt-engine.
But the way oVirt is designed is that it just pushes configuration to
the hosts - if your ovirt-engine dies, redeploying from backup should be
fairly quick and painless - just some features may be unavailable like
hot migrate etc, but importantly your existing VM's will continue to run
as they were until you can re-deploy your engine.
If you are worried about performance and resources - you could simply
create a new cluster for just Hosted Engine stuff and deploy it there,
so 2 servers in HA for engine separate from the rest of your VM clusters.

In addition to what others (correctly) said, we heard also of a few
setups using pacemaker etc. on bare-metal hosts for the engine.
I'd say, if you or your team are comfortable with pacemaker, have
conf/processes/experience around it, and can spare the extra hardware
and rack space, it might be a valid option.
Biggest con of ovirt-hosted-engine-ha, IMO, is the rather bad feeling
some people have about having less control on the disk image, etc.,
what to do when it dies, how to debug/fix issues. Of course, if you
are very experienced with oVirt's HA, know how to debug/fix corrupt
disk images, VM boot problems, etc., and have no experience with
pacemaker, oVirt HA will be better for you. In any case, for important
setups, keep good backups (and test them routinely!).
Best regards,
