[Users] Logical Network VLAN Tagging and DataCenters

[Simon Barrett]

Is it possible/supported to have the same VLAN ID defined across multiple datacenters logical networks?

I am seeing a situation where if I have two Datacenters, both with a logical network that have the same vlan tag. E.G.

DC = London, Logical network = prod, VLAN = 123
DC = Paris, Logical network = prod, VLAN = 123

If I edit one of the VM's running in the "London" datacenter, the VM NIC shows up as empty even though if I click on the VM and go to the "Network Interfaces" tab at the bottom of the screen it lists up the "prod" network under "Network Name".

All works OK for VM's that are assigned a logical network that is only defined once (i.e. has not been added to both datacenters).

This configuration is on oVirt Engine 3.3.2-1.el6. I am planning on moving to 3.4 very soon so will test out again on that version.

Thanks,

Simon
