I'm not sure if this will work if you have a tagged and untagged logical 
network.

Your vm should be able to communicate with your firewall if you did 
configure network correctly:
- configure VLAN on firewall interface
- configure VLAN on oVirt hosts (done by oVirt automatically)
- set switch ports to tagged for VLAN 2

As said I'm not sure if your mix of migration and blue network will 
work. In my environment my (cheap) switches can't deal with a port where 
tagged and untagged traffic is sent.
