[Bug 1893221] [NEW] SRIOV live migration does not consider instance NUMA topology for the device claim on the destination
Public bug reported:
None is passed[1] as an InstanceNUMATopology to
pci_tracker.claim_instance() in the ResourceTracker. This is called from
the SRIOV live migration codepath [2]. This will cause that the dest
host PCI claim check will not consider the NUMA topology of the
instance.
