Service is unavailable at this time. (HTTP 409) (Request-ID: req-d76e2ba5-57eb-4ae9-8ce3-58dd76b64896)
~~~
However this validation is bypassed if nova-compute on the source compute node has maintenance enabled,
and this results in migration stuck in pre-migrating status.

Version-Release number of selected component (if applicable):
How reproducible:
Always
Steps to Reproduce:
1. Create an instance
2. Shutdown the compute node where the instance is started
3. Enable maintenance of the nova-compute service on the source compute node
4. Migrate the instance
Actual results:
Migration is accepted but gets stuck in pre-migrating status
Expected results:
Migration is rejected
