Adam Litke has uploaded a new change for review. Change subject: Live Merge: Update drive.format after active layer merge ......................................................................
Live Merge: Update drive.format after active layer merge A merge of the active layer can change the drive format from cow -> raw if a snapshot was merged into a raw backing file. In that case we must correct the VM Drive metadata to ensure the drive is handled properly after the merge has finished.
