Never used it productive byself, but expect it was (is) used with typical 
SCSI stack (i.e. FC, iSCSI etc.) HA setups like here:
http://www-archive.xenproject.org/files/xensummit_fall07/19_Matsumoto.pdf

at least in that doc Fijutsu stated pvSCSCI as follows in a "older" 
presentation:

--- snip ---
- pvSCSI driver on driver domain is under evaluation.
-? pvSCSI driver works on HVM domain and PV domain.
--- snap ---


i.e. "current" 5.8.5 linux kernel states in "drivers/xen/Kconfig":

--- snip ---
config XEN_SCSI_BACKEND
        
   tristate "XEN SCSI backend driver"

   depends on XEN && XEN_BACKEND && TARGET_CORE

The SCSI backend driver allows the kernel to export its SCSI Devices to other 
guests via a high-performance shared-memory interface.
Only needed for systems running as XEN driver domains (e.g. Dom0) and if 
guests need generic access to SCSI devices.

so i would give it a try...ß)
