Description of problem: Based on code analysis and reports [1] from a customer deployment (in testing, thankfully), the fix [2] for bz 1389284 breaks migrations, perhaps only limited to migrations of VMs with SRIOV cards passed through. Version-Release number of selected component (if applicable): openstack-nova-13.1.2-6.el7ost How reproducible: Always, presumably. Steps to Reproduce: 1. Attempt to cold-migrate a VM with an SRIOV card passed through. Actual results: Fail with 'MigrationContext' object has no attribute 'old_pci_devices' Expected results: Migration succeeds [1] https://bugzilla.redhat.com/show_bug.cgi?id=1389284#c8 [2] https://code.engineering.redhat.com/gerrit/#/c/88986/
We're missing [1] in rhos9 - that's the patch that introduced version 1.1 of the MigrationContext, which added the old_pci_devices and new_pci_devices fields to the object. It's a big patch - 240 lines spread over a dozen files, so its backportability remains to be determined. In the meantime, we need to revert [2] out of rhos9.
