You could something like this (IIUC):
dead_snap1_params = types.Snapshot(
description=SNAPSHOT_DESC_1,
persist_memorystate=False,
disk_attachments=[
types.DiskAttachment(
disk=types.Disk(
id=disk.id
)

Hi, thanks for your input!
It seems I was able to reach my target
What I've done
# Locate the service that manages the disk attachments of the virtual
# machine:
disk_attachments_service = vm_service.disk_attachments_service()
# Retrieve the list of disk attachments and then the bootable disk
disk_attachments = disk_attachments_service.list()
bootdisk = None
for disk_attachment in disk_attachments:
disk = connection.follow_link(disk_attachment.disk)
if disk_attachment.bootable == True:
bootdisk = connection.follow_link(disk_attachment.disk)
break
snaps_service = vm_service.snapshots_service()
snap = snaps_service.add(
snapshot=types.Snapshot(
description=snap_description,
persist_memorystate=False,
disk_attachments=[
types.DiskAttachment(
disk=types.Disk(
id=bootdisk.id
)
)
]
),
)
logging.info(
'Sent request to create snapshot \'%s\', the id is \'%s\'.',
snap.description, snap.id,
)
It seems also the monitor function already present in backup.py of the sdk
examples linked in my previous message is working ok,
# Poll and wait till the status of the snapshot is 'ok', which means
# that it is completely created:
snap_service = snaps_service.snapshot_service(snap.id)
while snap.snapshot_status != types.SnapshotStatus.OK:
logging.info(
'Waiting till the snapshot is created, the status is now
\'%s\'.',
snap.snapshot_status,
)
time.sleep(1)
snap = snap_service.get()
logging.info('The snapshot is now complete.')
In fact in the log file I have
INFO:root:Sent request to create snapshot
'padnpro_imp-backup-0e0c7064-bec5-429b-9ad7-cd8d1e5b25be', the id is
'4135e8cb-87e8-4f09-82f5-b9ad0ed2f5be'.

What if I would like to emit an event if for any reason the creation of the
snapshot doesn't complete in a predefined elapsed time and manage it?
I think I have also to manage the case when for any reason no disk is
marked as bootable inside the VM I'm backing up...
