Hmmm...
I was able to sync ovirtmgmt network on two hosts out of three but now I 
have a problem starting engine up on those two nodes

as I mentioned earlier file 
/etc/sysconfig/network-scripts/ifcfg-ovirtmgmt gets removed from those 
two nodes after syncing.

How can I recreated that ifcfg-ovirtmgmt file?
