Is it possible/supported to have the same VLAN ID = de=3D fined across multiple datacenters logical networks?

I am seeing a situation where if I have two Datace= nt=3D ers, both with a logical network that have the same vlan tag. E.G.

DC =3D3D London, Logical network =3D3D prod, VLAN = =3D3D 12=3D 3

DC =3D3D Paris, Logical network =3D3D prod, VLAN = =3D3D 123=3D

If I edit one of the VM’s running in the = 22=3D 0;London” datacenter, the VM NIC shows up as empty even though if I c= =3D lick on the VM and go to the “Network Interfaces” tab at the bo= =3D ttom of the screen it lists up the “prod” network under “= =3D Network Name”.

All works OK for VM’s that are assigned a lo= gi=3D cal network that is only defined once (i.e. has not been added to both data= =3D centers).

This configuration is on oVirt Engine 3.3.2-1.el6.= I=3D am planning on moving to 3.4 very soon so will test out again on that vers= =3D ion.

Thanks,

Simon
