Public bug reported:
Steps to reproduce
==================
1) Set the [upgrade_levels]/compute config parameter to '5.0'
2) Boot a simple instance
3) Prepare your env that the first destination host for the next migration will
fail during _prep_resize (for example the resize_claim fails)
4) Do the migration
Expected result
===============
The migration is re-scheduled to an alternative host where it succeeds.
Actual result
=============
The migration fails, the instance goes to ERROR state, and the log
contains a nice stack trace:
