RHEV3 : cluster power saving question

Hi,

During the Lab3, I have configured and tested cluster power settings... all goes well.

However, I have one question, after migrating all VMs to a same host, why empty host is not powerred off?

(Of course, I have configured and tested power management for the 2 hosts).

Is there something else to do so that to get the host get automatically powerred of?

Regards
