I'm experimenting with VLANs in my oVirt test setup with 3.1. My ovirtmgmt, and storage network are each on a basic switch with no VLANs. On the other hand, my public network has several VLANs available to me. The network operations team created a trunk for me with 2 x 1 GbT ports, aggregated with LACP, and passed it on with all VLANs. In oVirt, if I bind the two network interfaces, and, and assign one IP to the bind (mode 4) without specifying a VLAN, everything works fine (untagged VLANS are assigned ID 494 which is what I want). On the other hand, if I specify VLAN 494 in the logical network setup (or any of the other VLANs), it fails. I don't see any traffic. Network operations says that all VLANs are passed on the trunk. How can I debug? Jason.
