Hey Guy's,

If I'm looking to setup the oVirt engine in an HA configuration off the physical servers hosting my VM's (non self hosted), what are my options here?

I want to setup two to four active oVirt engine instances elsewhere and handle the HA via something like haproxy / keepalived to keep the entire experience seamless to the user.

You will need to set up the oVirt engine service as well as the PG database (and ovirt-engine-dwhd service and any other service we run next to the engine) as highly available module.
In pacemaker[1], for example. 
You'll need to ensure configuration is also sync'ed between nodes, etc.

So already have one ovirt engine setup separately on a vm that manages two remote physical hosts.  So familiar with the single host approach which I would simply replicate.  At least that’s the idea anyway.  Could you please expand a bit on the highly available module and  syncing the config between hosts?

That's a different strategy, which is also legit - you treat this VM as a highly available resource. Now you do not need to sync the config - just the VM disk and config.
Perhaps something like https://www.unixarena.com/2015/12/rhel-7-pacemaker-configuring-ha-kvm-guest.html .

But if you are already doing that, I'm not sure why you'd prefer this over hosted-engine setup.
Y.

Cheers,
Tom



>From what I've seen in oVirt, that seems to be possible without the two oVirt engines even knowing each other's existence but is it something anyone has ever done?  Any recommendations in this case?

Having settings replicated would be a bonus but I would be comfortable if they weren't and I handle that myself.
