Howdy all,
we're testing ovirt at the moment, and trying to get power management working for the
dell PE1950's we're using as the hypervisors...
in RHEV3 beta, we used to use the console IP, U&P and type "ilo3" to monitor
power states etc..
in the ovirt manager, trying to set the same config up - it says
Test Failed (unknown error).
and in the engine.log it shows
2012-02-02 02:34:09,385 ERROR [org.ovirt.engine.core.bll.FencingExecutor]
(http--0.0.0.0-8080-2) Failed to run Power Management command on Host , no running proxy
Host was found.
Any ideas?
Cheers
Spyro

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.

Hi,
Yes, the ovirt backend does not shut down or power up any hosts directly, it can work only
through vdsm. Therefore you need one running host per datacenter to be able to manage the
rest of the hosts.
I understand the motivation, but for smaller installations I believe it would be so great
if the backend could do it as well. What vdsm does in the background is not much more than
calling the ipmipower command.

I agree, there is no real reason not to fence hosts from the management
host, yet another feature we would love to have.
Worth checking if the engine can reuse the vdsm code for fencing.

This would come for free once we have the all in one (vdsm running on the same host as
engine).

We'll get it for 'free' when installing VDSM on the same host as the
engine, but the above can be useful even if the user don't install VDSM
on the engine machine.

I was suggesting that vdsm always be installed on the same host as there are other such
services that the engine could benefit from...

Yeah, that may be an easy solution, we could just use the vdsClient to run commands in
local, but that would also bring all of vdsm's dependencies, like libvirt to the
engine node. Or maybe the fence-agents package could be enough?

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..

perfect - confirmed that adding the 2nd host to the cluster enabled me to configure the
