When using DVR-SNAT, a simple neutron-l3-agent gateway restart triggers this issue.
Reproduction Note: Nodes with an ACTIVE or BACKUP (in the case of L3HA) router for the network are not affected by this issue, so a small 1-6 node environment may make this difficult to reproduce or only affect half of the nodes (e.g. 3/6 nodes if you have L3HA). Workaround: for each compute node, you need to create a new VM on each network. While registering the new VM port it will cause the missing fpr/rfp interface pair to be created and paired. It does not seem possible to fix it any other way such as stopping/starting the existing VM, rebooting the host, etc. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1894843 Title: [dvr_snat] Router update deletes rfp interface from qrouter even when VM port is present on this host To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-archive/+bug/1894843/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
