Open Stack

For an Openstack VM instance, if its backing image got deleted
already, and this VM instance was already hard rebooted, and went into
`Error` state due to `Image not found` error.

Is it possible to recover this VM stucking in this bad state? I tried
to create a vm snapshot, and then try to rebuild this VM using the
newly created vm snapshot, and it kept failing.
