commit b197f7c1c4b9c0dd4c58f5c5a4b654dde5596b85 Author: Adrian Chiris <[email protected]> Date: Thu Jan 31 18:51:33 2019 +0200 Delete port binding level for deleted bindings Today, if live migration has failed after an inactive binding was created on the destination node but before the activation of the created binding, the port's binding level for the destination host is not cleared during nova's API call to neutron to delete the port binding. This causes future attempts to perform live migration of the instance to the same host to fail. This change removes port binding level object during port binding deletion. Closes-Bug: #1815345 Change-Id: Idd55f7d24a2062c08ac8a0dc2243625632d962a5 ** Changed in: neutron Status: In Progress => Fix Released -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1815345 Title: neutron doesnt delete port binding level when deleting an inactive port binding Status in neutron: Fix Released Bug description: When performing VM live migration with a normal port (OVS mechanism driver) nova creates an in-active binding on the destination node then activates that binding upon successful migration. in case of failure to migrate with libvirt, an exception is raised, nova performs a rollback operation for the live migration and instance remains in running state on the source node. part of the rollback operation is deleting neutron's port binding on the destination node with the following API call: DELETE /v2.0/ports/{port_id}/bindings/{host_id} this call, for an inactive port binding (which was never activated), does not delete the port's binding level which causes future migration attempts to fail. Reproduction setup: - devstack deployment of an all in one and a compute node from master - OS: FC28 - QEMU hypervisor - neutron OVS mechanism driver enabled - perform further configurations to enable live-migration : https://docs.openstack.org/nova/pike/admin/configuring-migrations.html - block libvirt migration port with iptables on destination node (on my setup i just needed to activate iptables on destination node) reproduction steps: http://paste.openstack.org/show/744802/ To manage notifications about this bug go to: https://bugs.launchpad.net/neutron/+bug/1815345/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : [email protected] Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
