The powersaving policy is only applicable to the hosts, so if your low =

it should place the host into maintenance and migrate the paused vm (may =

I mean that I know that I can set a power saving policy, it is a very =
nice thing.
I need to be sure that I can pause/suspend (not shutdown) virtual =
machines.
I also need that, if I suspend enough virtual machines ovirt shutdowns =
server to save power following the power save policy.
=20
Otherwise is it possible to manually shutdown a server forcing ovirt to =
migrate vms to the only one powered up?
=20
Basically it is a "manual power saving" mode.
=20
Thanks again,
Mario

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
2015-01-13 12:45 GMT+01:00 Artyom Lukianov <alukiano(a)redhat.com>:
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=3D0 and
HighUtilization=3D50, 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.

Subject: [ovirt-users] Ovirt and power saving
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
