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.

On which release is this happening? I believe the console.log ownership issue has been fixed in newer releases.
