I am running KVM guests under Redhat 6. I tried to setup a bridge device to an interface with a vlan trunk connected to a Juniper switch. On the KVM host, I am able to define vlans and access them via the vlan trunk. I was not able to access a vlan from the kvm guest connected to the bridged interface. I believe this would be what is commonly called QinQ or 802.1ad. Is this possible to do? I am using virtio drivers.
If I can't do this, I guess I will end up with alot of bridged vlans. I tried doing this a while back under the vmware server and it did not work either. I think the reason that it did not work had something to do with arp resolution. I believe I read some where that it may be possible under ESXi.
Thanks, Nataraj

After thinking about this further I guess it would look like somehow being able to configure a "port" (the one connected to the kvm VM) on the linux bridge as being a vlan trunk. Alternatively, if the guest (also running linux) were able to support QinQ I think I could configure QinQ on the guest as well as on the port on the Juniper switch, though that would only work with 1 guest, so the first solution would be preferred.
