Bug Description
The pre_live_migration API is called with a disk retrieved by a call to driver.
As a result, for example when migrating a volume with a NFS volume attached, a useless file is created in the instance directory.

Hi Thomas, well I think the bug impact is much worse. After migration, the VM uses a local copy of the "shared" volume. This is very bad, since any data written on the volume will be discarded once the VM has been destroyed.
