I am bringing my new system online as I am typing this message… Hopefully I can get my power management to work with my blade center… if anyone knows how with drac5 please let me in ;)

Thanks it is the exact reply I was hoping for I cannot test on my deployment, I am already down too many machines… however if you wait a couple days I can get you’re an answer as to whether it works on my deployment or not J It would be the icing on the cake!

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.
