rhevm network persistence issue

Today I observed a strange issue due to host non operational

>Tried service vdsmd restart but there was another issue with rhevm network which went down and was not coming up:

I had to recreate /etc/sysconfig/network-scripts/ifcfg-rhevm (it was trying dhcp for ip addressing) from another host.

Also I had to re create  bond0 at /var/lib/vdsm/persistence/netconf/bond and rhevm at /var/lib/vdsm/persistence/netconf/nets
