Thanks for the bug report, couple of questions: > Live-migration of DPDK VMs from compute node 13 to 16. fails. Cold migration works fine. Please tell me that you mean RHEL 7 to RHEL 8, and that all OSP containers have been upgraded to OSP 16. Running both OSP 13 and OSP 16 compute containers at the same time in the same deployment has never been supported. > Expected results: > Workload should migrate to osp16.1 compute node to perform upgrade You filed this bug under documentation. As part of [1], of which this BZ is a double-duplicate of (this BZ is a duplicate of 1902631, which is itself a duplicate of 1916869), we already documented that live migration of OVS-DPDK instances during FFU is not supported [2]. What is your expectation in filing this BZ? We're not going to do any more code fixes for 16.1 or 16.2...

Running both OSP 13 and OSP 16 compute > containers at the same time in the same deployment has never been supported. Yes, this is the case, as you mentioned, I cloned this bug from an original bug. After updating operating system to RHEL 8, we can not live migrate workload from RHEL 7 host. > > > Expected results: > > Workload should migrate to osp16.1 compute node to perform upgrade > > You filed this bug under documentation.

What is your expectation in > filing this BZ? We're not going to do any more code fixes for 16.1 or 16.2... We have cloned this bug to mention it in the 16.2.6 release notes if it is not present. Our team asked the openvswitch team about this issue, and we were told they were not expecting this to work (we also have asked in the Nova channel, and we were told that the worst case scenario, cold migration, is still supported). > > [1] https://bugzilla.redhat.com/show_bug.cgi?id=1916869 > [2] > https://gitlab.cee.redhat.com/rhci-documentation/docs- > Red_Hat_Enterprise_Linux_OpenStack_Platform/-/merge_requests/6001/diffs |
