You can just teach the get_scsi_devicetype() helper to recognize the
special syntax and compare by storage type in that case (can/should be
it's own patch ;)). At a glance, 'iscsidirect' and 'zfs' are the ones
using an "iscsi://" path, but please double check. Of course there could
be a third-party plugin using "iscsi://" too, but this is just an early
check and only applies to VMs with machine version < 4.1 anyways. These
cases should be very rare and it'll just fail later so no big deal. The
benefit of having the check earlier for all other cases is enough to
justify that IMHO.
