Re: [ovirt-users] How power-saving schedule policy applied?

[Martin Sivak]

Hi,

and here is a fresh screenshot just for you :)

You need to edit the cluster, select scheduling policy tab and add two
parameters to your Power saving policy. One enables the power cycling
mechanisms and the second one (HostsInReserve) controls how many empty
hosts are allowed to stay up. When the host is not empty anymore a new one
will be started.

Best regards

I suppose that power saving policy should converge VMs into hosts one by one. Something like that. From the beginning, all hosts are in ‘power off’ state, if a VM launch, power saving scheduling module should power on one host, and assign VM into that host. With many VMs activated, exceeding the threshold, power saving scheduling module should turn on another host…Jepp, that's basically how it works:)/K If anyone had played power saving scheduling policy, please share me your scenarios or some hints.
