<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We are in advance stage of resolving migration with SR-IOV and to improve the coverage in that part.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We have proposed the following patches to fix SR-IOV migration and its race conditions:<o:p></o:p></p>
<p class="MsoNormal">[1] - Allocate PCI devices on migration: <a href="https://review.openstack.org/#/c/328983">
https://review.openstack.org/#/c/328983</a><o:p></o:p></p>
<p class="MsoNormal">[2] - Update binding:profile for SR-IOV ports - <a href="https://review.openstack.org/#/c/242573/">
https://review.openstack.org/#/c/242573/</a><o:p></o:p></p>
<p class="MsoNormal">[3] - Update available resources before confirm stage - <a href="https://review.openstack.org/#/c/327356/">
https://review.openstack.org/#/c/327356/</a><o:p></o:p></p>
<p class="MsoNormal">[4] - Fix revert on migration with SR-IOV - <a href="https://review.openstack.org/#/c/326174">
https://review.openstack.org/#/c/326174</a><o:p></o:p></p>
<p class="MsoNormal">[5] - Fixes for race conditions in revert migration with SR-IOV -
<a href="https://review.openstack.org/#/c/339765/">https://review.openstack.org/#/c/339765/</a><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We added a job for Mellanox CI for SR-IOV multi node. The Job is called Nova-ML2-Sriov-Multinode<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">To allow the multi node Job with direct port (or any port type) we need [6] to be merged in tempest<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">[6] - Fixed manager.py to support multinode test on vnic_port -
<a href="https://review.openstack.org/#/c/335447/">https://review.openstack.org/#/c/335447/</a><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Also we added basic migration test in tempest [7] that passed in the SR-IOV multimode see log [8]<o:p></o:p></p>
<p class="MsoNormal">[7] - <a href="https://review.openstack.org/339230"><span style="color:windowtext;text-decoration:none">Add connectivity check test for migration</span></a> -
<a href="https://review.openstack.org/#/c/339230/">https://review.openstack.org/#/c/339230/</a>
<o:p></o:p></p>
<p class="MsoNormal">[8] - <span style="color:#1F497D"><a href="http://13.69.151.247/MN_migrate/">http://13.69.151.247/MN_migrate/</a><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal">Of course we plan to add more test like migration-revert and etc.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It would be wonderful if we can get some reviews from the nova/tempest community to land all this patches in this cycle.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
<p class="MsoNormal">Moshe. <o:p></o:p></p>
