AFAICT MSI-X is not supported on the mpt-fusion SAS device when running
on the KVM host..

Yeah, the log attached was using the SATA SSD with the IBLOCK export
(the one that worked..). The exception that I was seeing from pSCSI
export from the same SATA SSD from within KVM Guest running v2.6.29.2
involved a non-zero return from
drivers/scsi/scsi_lib.c:scsi_execute_async() for basically all bulk
struct scatterlist I/O (the control path seemed OK however).

Unfortuately, scsi_execute_async() was (it has been removed for v2.6.30)
really bad at returning any useful value and hardcodes a return of
'DRIVER_ERROR << 24' in the error path, so I was unable to determine
anything useful for what was actually causing it to fail during my
initial testing..

I will keep poking at it and see if I can find anything interesting..

Thanks for the pointer, I will have a look.

Many thanks for your most valuable of time,
