Dear Alex,

Thanks for your kind response! So its mandatory to enable power management? Is that a good way to enable power management in running hosts or already installed hosts in Ovirt? If possible, let me know the benifits of using power management; 
Yes, you need power management and it can be configured at any time. It is needed so as the highly available VMs to be restarted at another host, when one host fails and avoid having zombie VMs in unresponsive state as you faced. Power management is means for the hosts to ensure the state of each other and is a must for high availability.

Thanks in advance!

Best Regards,
Hariharan
