Subject: [PATCH] virDomainCheckpointRedefinePrep: Set 'current' checkpoint if
there isn't any
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When redefining checkpoints from scratch we'd not set the 'current'
checkpoint if there wasn't any. This meant that the code wasn't ever
able to set a 'current' checkpoint as any other one looks up if the
parent of the redefined checkpoint is current.
Since the backup code then requires the current checkpoint to start the
lookup we'd not be able to perform a backup after restoring the
checkpoint hierarchy.
