[Bug 1825205] [NEW] when the last vm of a network in a compute is live-migrated with DVR enable, the qrouter namespace is not deleted

 

Public bug reported:

Router with DVR, when last vm connected to subnet is live-migrated from compute node to another compute node, qrouter- namespace isn't cleaned.
In similar situation when VM is migrated with "nova migrate" (cold migration) or removed than qrouter- namespace is removed properly from compute node.

         Status: Confirmed
