Stephen Finucane 10f0a42de1 tests: Add reproducer for bug #1879878
When one resizes a pinned instance, the instance claims host CPUs for
pinning purposes on the destination. However, the host CPUs on the
source are not immediately relinquished. Rather, they are held by the
migration record, to handle the event that the resize is reverted. It is
only when one confirms this resize that the old cores are finally
relinquished.

It appears there is a potential race between the resource tracker's
periodic task and the freeing of these resources, resulting in attempts
to unpin host cores that have already been unpinned. This test
highlights that bug pending a fix.

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:

Developers

For information on how to contribute to Nova, please see the contents of the CONTRIBUTING.rst.

Any new code must follow the development guidelines detailed in the HACKING.rst file, and pass all unit tests.
