It's interesting, I have an opposite opinion. I don’t see why oVirt
reinvents its own HA instead of using Pacemaker. And it’s not old, it’s
mature ;)

I my case, I had no option to setup Hosted Engine since migration to oVirt
required storage rearrangement. Now I have to run HA oVirt VM using
Pacemaker + DRBD. Works great.

Would be great if you can share more information about your setup.
It's a great topic for an ovirt.org blog post, for example.

Honestlly I don't see why in 2017 people still using the old DRBD +
Pacemaker solution for virtualization stuff.

Thanks, I agree bad idea to execute virsh command without knowing vdsm and
engine.

Is their any plan in ovirt to support *drbd + Pacemaker* ?

When you come from libvirt and you know what to do, you might not want to
find/read a dedicated documentation for such a little query.

yes, sure, for read-only

but for any modification, no matter how minimal, it’s almost always needed
to inform vdsm/engine to know about it to prevent corner cases,
misdetections, etc...

Use at your own risks:

vdsm at ovirt:shibboleth

But, you may unsynchronize your host HW with engine database.

it is almost always a bad idea to do that

hooks are exactly for the cases like below, just in a cleaner way

It is preferable you use VDSM hooks to add devices to VMs.

If you only need read access then you need to supply -r as an additional
argument.

Why do you need virsh because that will only give you the info on that
host, using ovirt-shell gives you the info for all hosts.
