Hi,
     I forgot to backup the ifcfg-eth0 for ovirtmgmt but i think ONBOOT 
was probably not there.
BTW, before i attach any files here, is there a way to remove the host 
and re-discover it afresh ?
ovirt web gui does not give me any option to remove.. the Remove is 
diabled and host is in Non Responsive state.
How do i remove and start from scratch and then i can try to see if i 
can fix ifcfg-eth0 for ovirtmgmt ? Currently i am unable to remove the host.
