Hello,
Could you tell me more about this Error:* Failed to
RedefineVmCheckpointsVDS, error = General Exception: ('Property xml is
required',)*. It happened on creating incremental backup using ovirt sdk.
This error means that you have a checkpoint that was created during one of
your previous backups that missing the checkpoint XML in the DB, this XML
is needed in order to redefine the checkpoint on the host after the VM
powered-off.
This situation shouldn't happen if the the backup that created
checkpoint '6a569f20-f1e4-469a-8982-7f8cbfbbfc9e' was successful.
Did you enable the incremental backup feature before you took the first
backup for that VM?
# engine-config -s "IsIncrementalBackupSupported=true"
# systemctl restart ovirt-engine
Do you have the logs for the backup that created checkpoint
'6a569f20-f1e4-469a-8982-7f8cbfbbfc9e'?
Can you please provide the content of the checkpoint from the DB?
*select * from vm_checkpoints where
checkpoint_id='6a569f20-f1e4-469a-8982-7f8cbfbbfc9e'*
How can I fix it? I know that is not because of wrong checkpointId
because
I tried to use wrong Id on other environment and logs are different.
In case of a problem when trying to redefine one of the checkpoints, a full
backup should be taken for the VM.

Here you can see that the engine reports the checkpoint redefinition failed
and a full backup should be taken.
