I looked through the logs and did not see anything of interest. Then all of a sudden the problem fixed itself. Weird. Thanks for your help though.

Hi Guys,
We have two Ovirt clusters setup in one datacenter. Dev and Prod.
I have a situation where if I power off a VM in the Prod environment, it does not start up again.
I get the following when trying to run it ...
"Failed to run VM tuskweb-prod-02 (User: admin@internal)."
"Error while executing action Run VM once: Network error during communication with the Host."
Odly enough, if I move the down VM to the Dev cluster and run it again, it starts up fine.
I've had this problem with 2 VMs this far (on different nodes in the cluster). Im afraid to bring any more VMs down as they may not start back up.
Any help is appreciated.
Thanks,
Usman
