[Users] Power Management question

[Spyro Polymiadis]

so, if i read that right - does this mean that i need to have 2 nodes in the cluster to get this working (thats the only difference from the rhev environment) i havent moved the other hypervisors into it yet...
i figured the manager host could perform the power management..

Just a stab in the dark here... how many hypervisor nodes are running in
the same cluster?

The way fencing works (iirc) is if you want to fence HostA, you need to
have a separate HostB running so that HostB can issue the fence command
to HostA.  So if there's just a single node running, there's no one else
to proxy the fencing command to that host.  I don't think the oVirt
Engine server ever directly fences hosts, it just tells a remote vdsm to
do it on its behalf.
