Subject: [PATCH] virDomainCheckpointRedefinePrep: Set 'current' checkpoint if
|
|
|
a41c76 |
there isn't any

When redefining checkpoints from scratch we'd not set the 'current'
|
|
|
a41c76 |
checkpoint if there wasn't any. This meant that the code wasn't ever
|
|
|
a41c76 |
able to set a 'current' checkpoint as any other one looks up if the
|
|
|
a41c76 |
parent of the redefined checkpoint is current.
|
|
|
a41c76 |
|
|
|
a41c76 |
Since the backup code then requires the current checkpoint to start the
|
|
|
a41c76 |
lookup we'd not be able to perform a backup after restoring the
|
|
|
a41c76 |
checkpoint hierarchy.
