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.
Otherwise is it possible to manually shutdown a server forcing ovirt to migrate vms to the only one powered up? Basically it is a "manual power saving" mode.
