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...

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..
That's my understanding, but I could be wrong :) The vdsm/oVirt Engine folks would know better
Try moving a 2nd host over and see if that resolves the issue _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
