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.

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...

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.
