commit c198710dc551bc0f79851a7801038b033088a8c2 Author: Swaminathan Vasudevan <swaminathan.vasude...@hpe.com> Date: Thu Mar 31 17:48:09 2016 -0700 DVR: Moving router from dvr_snat node removes the qrouters Removing the router from dvr_snat node removes the qrouters that are servicing the VM and dhcp ports. If there are still dvr serviceable ports in the dvr_snat node, and if router remove command is executed to remove the router association from the dvr_snat agent then only the snat functionality should be moved to the the different agent and the router namespaces should be untouched. This patch checks if there are any dvr serviceable ports for the dvr router and if exists, it will not send a router_remove message to the agent, but instead will send an router_update message to the agent.

Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1564575 Title: DVR router namespaces are deleted when we manually move a DVR router from one SNAT_node to another SNAT_node even though there are active VMs in the node Status in neutron: Fix Released Bug description: DVR router namespaces are deleted when we manually move the router from on dvr_snat node to another dvr_snat node. It should be only deleting the snat_namespace and not the router_namespace, since there are 'dhcp' ports and 'vm' ports still serviced by DVR. How to reproduce: Configure a two node setup: 1. I have one node with Controller, compute and networking node with dhcp running in dvr_snat mode. 2. I have another node with compute and networking node without dhcp running in dvr_snat mode. 3. Now create network 4. Create a subnet 5. Create a router and attach the subnet to the router. 6. Also set a gateway to the router. 7. Now you should see that there are three namespaces in the first node. a. snat_namespace b. qrouter_namespace c. dhcp_namespace 8. Now create a VM on the first node. 9. Now try to remove the router from the first agent and assign it to the second agent in the second node. neutron l3-agent-router-remove agent-id router-id This currently removes both the snat_namespace and the router_namespace when there is still a valid vm and dhcp port. Suspect that checking for available DVR service ports might be causing an issue here. Will try to find out the root cause.
