Hello Hutson, Actually that's the expected behaviour of the 8021Q network drivers. We decided to keep the bridge and the physical device with the vlan tag in the host for the following reasons:
1) It doesn't hurt to leave the bridge and the tagged interface. It won't eat up system's resources. 2) If another VM with the same network ID is launched in the same host, you don't need to create it again, therefore (slightly) speeding up boot times Do you agree with this? Do you think the default behaviour should be to remove the bridge and tagged interface? Of course this behaviour can be modified by enhancing the clean script [1]. Take a look at the ebtables clean script [2]. You will probably need to develop a "deactivate" method in the ruby class that handles the 8021q network drivers [3].
