Re: [ovirt-users] Ovirt and power saving
Not really understand you, what you mean by "you can pause vm and so trigger the low
utilization parameter"?

Thanks for reply.
I just want now to be sure that you can pause vm and so trigger the low
utilization parameter

We have power saving policy that also have possibility to poweroff
hosts(via power management), you can configure power saving policy
parameters for you purpose(HighUtilization can have values from 50-100 and
LowUtilization 0-49), so you can set LowUtilization=0 and
HighUtilization=50, so load balancing will try migrate all vms on one
host(if cpu utilization less that 50). And also you can set parameter
"HostsInReserve" to 0 if you do not want additional hosts in reserve.

Hello,
I would like to ask if it is possible to do this use case with ovirt:
1) two servers powered on
2) operator suspend some virtual machines
3) load falls down
4) ovirt shutdown one server
Then operator unpauses virtual machines and ovirt starts again the 2nd
server.
Thanks,
Mario
