I'd seen "EnableAutomaticHostPowerManagement" mentioned in the docs, but couldn't find it.

I eventually figured out that I had to add the two attributes that Liran mentioned to the policy using the '+' button in the "Scheduling Policy" editor.

I've got a cluster made up of five physical hosts, (Dells with idrac 7 management)
Power management / fencing enabled on all hosts.

I've enabled the power_saving scheduling policy on my cluster, it's migrated all the VM's to a couple of physical hosts so three are sitting idle with no VM's.

Shouldn't the power_saving policy shut down the idle hosts?
Hi,
It should. In the cluster scheduling policy, did you set "EnableAutomaticHostPowerManagement" to be true? and setting "HostsInReserve" to a number of reserve idle hosts is also set?

Liran.
