Originally migration was not possible with vhost-scsi because as part of migration, the source host target SCSI device state needs to be saved and loaded into the destination host target SCSI device. This cannot be done by QEMU.
As this can be handled either by external orchestrator or by having shared-storage (i.e. iSCSI), there is no reason to limit the orchestrator from being able to explictly specify it wish to enable migration even when VM have a vhost-scsi device.
