Is it possible/supported to have the same VLAN ID defined across multiple d=
atacenters logical networks?
I am seeing a situation where if I have two Datacenters, both with a logica=
l network that have the same vlan tag. E.G.
DC =3D London, Logical network =3D prod, VLAN =3D 123
DC =3D Paris, Logical network =3D prod, VLAN =3D 123
If I edit one of the VM's running in the "London" datacenter, the VM NIC
sh=
ows up as empty even though if I click on the VM and go to the "Network Int=
erfaces" tab at the bottom of the screen it lists up the "prod" network
und=
er "Network Name".
All works OK for VM's that are assigned a logical network that is only defi=
ned 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

Well I am also interested in this feature.
I assumed it would work as logical networks
are per data center defined.
I hadn't time and resources to test it yet.
Maybe this is just an UI-Bug?
Simon, could you try and get the network
interfaces of this vm via REST-API or cli?

Hi Simon,
I think what you're experiencing is this:
https://bugzilla.redhat.com/show_bug.cgi?id=1070835
So this is not by design, there shouldn't be any issue with having the
same VLAN ID defined across multiple DCs. Should be fine when oVirt
3.4.1 is released, or using nightly build.
Yours, Lior.

Looks very much like what I am seeing. Many thanks for the info. I'll test when 3.4.1
is available.
