Comment 4 for bug 1348811

I'm not related at all to the one who reported this bug, but I am able to reproduce simply by trying to resize a VM from Horizon. Since the resize process also does a migration, this bug affect the resize process during the migration step. Please note that I'm assuming this is the same bug because the error and symptoms are exactly the same.

That would mean provision vm -> open the "more" drop down menu -> click resize vm -> choose a bigger flavour -> look at the migration fail and the error show up in the logs.
