I think that this has been already asked: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/USPMFD3NUAGE4PLOV62HSQDNEMHL37TU/?sort=date

It is not supported because of how traffic is passed to a vlan by its base interface.

When packets arrive to the nic and on top of it there is a vlan, any packet with a tag that matches that vlan will be forwarded to it and from there to the bridge.

Leftovers (any other tags or non tag packers) will get forwarded to the bridge which is directly connected to the nic.

So you cannot have one tag and one untag using the same base interface (bond in your case).

Thanks,

Edy.

That sounds like a valid configuration. Edy, what do you think?

Correct. On the host i have 1 management interface (ovirtmngmt) and 1 bonded pair of 10GB interfaces (bond0)

Under Networks I have created the following networks.
VLAN70 - Tagged with 70
20GBBond - no tagging

In the host I added both VLAN70 and 20GBBond via the Setup Network. I dragged the two networks interfaces and dropped on the bond0 nics.

I created two VMs and assigned interfaces.
Test1 - Attached VLAN70
I ping 10.0.70.1 (the gateway) and it works.

Test2 - Attached 20GBBond and create a eth1.70 interface in the OS.
I can not ping 10.0.70.1, since VLAN70 is attached to Test1.
If I stop Test1, remove the VLAN70 and delete the VLAN70 network I can then ping 10.0.70.1 from the eth1.70 interface on Test2.
However, both can not exist at the same time.
