commit 33c8af1f8c46c9c37fcc28fb3409fbd3a78ae39f Author: Rodrigo Barbieri <[email protected]> Date: Wed Mar 31 11:06:49 2021 -0300 Error anti-affinity violation on migrations Error-out the migrations (cold and live) whenever the anti-affinity policy is violated. This addresses violations when multiple concurrent migrations are requested. Added detection on: - prep_resize - check_can_live_migration_destination - pre_live_migration The improved method of detection now locks based on group_id and considers other migrations in-progress as well.

Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1821755 Title: live migration break the anti-affinity policy of server group simultaneously Status in OpenStack Compute (nova): Fix Released Bug description: Description =========== If we live migrate two instance simultaneously, the instances will break the instance group policy. Steps to reproduce ================== OpenStack env with three compute nodes(node1, node2 and node3). Then we create two VMs(vm1, vm2) with the anti-affinity policy. At last, we live migrate two VMs simultaneously. Before live-migration, the VMs are located as followed: node1 -> vm1 node2 -> vm2 node3 * nova live-migration vm1 * nova live-migration vm2 Expected result =============== Fail to live migrate vm1 and vm2. Actual result ============= node1 node2 node3 -> vm1,vm2 Environment =========== master branch of openstack As described above, the live migration could not check the in-progress live-migration and just select the host by scheduler filter. So that they are migrated to the same host.
