I managed to know the root cause of this issue.
It is because ObjectType "25" from original backupset wasn't import by
bscan to target bareos, they appeared "0" in RestoreObject table ->
ObjectType col for all /VMS/XXXXX.metadata , therefore, when the ovirt
plugin trying to retrieve the effective_size from disk_metadata from
RestoreObject table, it will return null.
*The current workaround is manually patch the ObjectType to 25 for those
VMS RestoreObject after bscan.*
Another issue encountered from PluginName tinyblob column type can't fit
all plugin data into the column, and ultimately trimmed the VM name during
ovirt restore.
*The current workaround is modify the PluginName col to longblob.*
