Seeing that here:

I'm not sure if this is a job config issue or a bug in the code.

libvirtError: Operation not supported: Selecting disks to migrate is not implemented for tunnelled migration
It's most likely a problem with the job because CONF.libvirt.live_migration_tunnelled is not set, so it uses:
cfg.StrOpt('block_migration_flag',
default='VIR_MIGRATE_UNDEFINE_SOURCE, VIR_MIGRATE_PEER2PEER, '
'VIR_MIGRATE_LIVE, VIR_MIGRATE_TUNNELLED, '
'VIR_MIGRATE_NON_SHARED_INC',
help='Migration flags to be set for block migration',
deprecated_for_removal=True,
deprecated_reason='The correct block migration flags can be '
'inferred from the new '
'live_migration_tunnelled config option. '
'block_migration_flag will be removed to '
'avoid potential misconfiguration.'),
Which includes the VIR_MIGRATE_TUNNELLED flag, which apparently fails if you pass device_names to migrateToURI3.
Looks like this is a duplicate of bug 1441054.
