Live migration is currently totally broken if a NUMA topology is present. This affects everything that's been regrettably stuffed in with NUMA topology including CPU pinning, hugepage support and emulator thread support. Side effects can range from simple unexpected performance hits (due to instances running on the same cores) to complete failures (due to instance cores or huge pages being mapped to CPUs/NUMA nodes that don't exist on the destination host). Until such a time as we resolve these issues, we should alert users to the fact that such issues exist. A workaround option is provided for operators that _really_ need the broken behavior, but it's defaulted to False to highlight the brokenness of this feature to unsuspecting operators.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
