I am having some issues wrapping my head around this but what I am trying to setup is a A/B testing environment with a 3node cluster.  Each node has 2 nics, 1 for ovirtmgmt and 1 for vlaned A/B network.  I guess what I am trying to understand is if ovirt is tagging the vlan's I setup and is properly passing that to the switch?  This would allow me to have multiple subnets on a host that the switch also can see as multiple vlans.  Right?  I would still have to configure the switch to allow that port access to both vlans.
