Public bug reported:
With DVR, the qrouter- and snat- namespaces are deleted after the last
VM using the router is deleted. But the namespaces remain on the node
afterwards.
How the problem is reproduced;
1. Create a network, subnet, and router:
- neutron net-create mynet
- neutron subnet-create --name sb-mynet mynet 10.1.2.0/24
- neutron router-create myrouter
- neutron router-interface-add myrouter sb-mynet
- neutron router-gateway-set myrouter public
2. Create a VM:
- nova boot --flavor 1 --key-name <key> --image <cirros-image> --nic
net-id=<mynet-uuid> vm1
After the VM comes boots up, check the VM is pingable
3. Delete the VM.
The router's namespaces remain on the node. They should have been
deleted.
