guests are virtio-scsi, lsisas1078, and vmpvscsi.

The lsilogic adapter is known to be buggy/incomplete.  ibmvscsi is for
POWER, not x86_64.

That said, I'd still only rely on virtio-scsi for production systems.
I am confident there is development effort behind virtio-scsi to fix
bugs and so on.  With the other adapters it's more of a best-effort
scenario.
