Public bug reported:
Description
===========
I resize an instance and revert it, it works correctly, but when I resize this
instance again, the instance set to error, and I check the compute log like
below.
I use the rbd backend, I think the reason should be like this, If instance use
shared storage, revert resize will not delete the instance dir and files on
destination host, this files owner is root, if resize the instance again and
migrate to the same destination host, the IOError exception will be thrown.
