Hi oVirt Users and Admins !!!
I am installing ovirt 4.0.3 and do above conf on my OVirt Node using bond
and vlan.
When I add this host to ovirt engine and associate ovirtmgmt network with
same tag vlan number 1051, DNS conf was overwrited by vdsm.
So, as i do not find any way to set DNS on ovirt engine network conf i
think that for ovirt nodes i need to use another network that i do not plan
to use with virtual machines ( because if i add a new network on ovirt
engine with same tag vlan number the ovirt node conf will be overwrited by
vdsm ).
Before add to ovirt engine :
