[Users] Vlan interface on top of bonding

Hi, I'm new to ovirt and I'm dealing with network configuration. I have a host with a bonding of 4 eths and on top of that I added ovirtmgmt interface. I now want my vm to work on vlan 128 so I added the nic to ovirtmgmt bridge. I have access to vlan 1 (the bridge to the bond) but even if I add the vlan interface into the vm, I have no network traffic on vlan 128. I've created a new network in the cluster for vlan 128 but the web UI is not allowing me to add it on top of oviftmgmt (which I can do manually in the host but then I can't add it to the vm as a new nic because it only shows the ovirtmgmt interface). Is there a way to do this by cli? Regards,
