Hi all, We are in advance stage of resolving migration with SR-IOV and to improve the coverage in that part.
We have proposed the following patches to fix SR-IOV migration and its race conditions: [1] - Allocate PCI devices on migration: https://review.openstack.org/#/c/328983 [2] - Update binding:profile for SR-IOV ports - https://review.openstack.org/#/c/242573/ [3] - Update available resources before confirm stage - https://review.openstack.org/#/c/327356/ [4] - Fix revert on migration with SR-IOV - https://review.openstack.org/#/c/326174 [5] - Fixes for race conditions in revert migration with SR-IOV - https://review.openstack.org/#/c/339765/ We added a job for Mellanox CI for SR-IOV multi node. The Job is called Nova-ML2-Sriov-Multinode To allow the multi node Job with direct port (or any port type) we need [6] to be merged in tempest [6] - Fixed manager.py to support multinode test on vnic_port - https://review.openstack.org/#/c/335447/ Also we added basic migration test in tempest [7] that passed in the SR-IOV multimode see log [8] [7] - Add connectivity check test for migration<https://review.openstack.org/339230> - https://review.openstack.org/#/c/339230/ [8] - http://13.69.151.247/MN_migrate/ Of course we plan to add more test like migration-revert and etc. It would be wonderful if we can get some reviews from the nova/tempest community to land all this patches in this cycle. Thanks, Moshe.
