backupxml2xmltest: Call 'virDomainBackupAlignDisks' before formatting output Call the post-processing function so that we can validate that it does the correct thing. virDomainBackupAlignDisks requires disk definitions to be present so let's fake them by copying disks from the backup definition and add one extra disk 'vdextradisk'.

backup: Allow configuring incremental backup per-disk individually The semantics of the backup operation don't strictly require that all disks being backed up are part of the same incremental part (when a disk was checkpointed/backed up separately or in a different VM), or even they may not have a previous checkpoint at all (e.g. when the disk was freshly hotplugged to the vm). In such cases we can still create a common checkpoint for all of them and backup differences according to configuration. This patch adds a per-disk configuration of the checkpoint to do the incremental backup from via the 'incremental' attribute and allows perform full backups via the 'backupmode' attribute. Note that no changes to the qemu driver are necessary to take advantage of this as we already obey the per-disk 'incremental' field. https://bugzilla.redhat.com/show_bug.cgi?id=1829829 Signed-off-by: Peter Krempa <pkrempa@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> 2020-06-25 14:16:14 +00:00			`<disk name='vdextradisk' backup='yes' type='file' backupmode='full'>`
