Hi Jeff,

FWIW, I'm about to complete a domU scsi driver for Xen (initiator, aka front-end). Additionally, I'm writing "the other side", the associated target (tunnel, aka back-end) for dom0-style kernels.
Neat! Is it a standard XenBus device? Does it use the existing blkfront/blkback ring queue? Do you have a sneak peak of the code you could possible point us to?
REgards,
Anthony Liguori
I was planning on sending it to linux-scsi for review this week, then figure out the best path to get it upstream. The basic message protocol draws heavily on native SCSI RPC model, and by that, I mean SAM and "SMP-ish". This allows communication with any number of SCSI targets/LUNs/etc. between any domU or dom0. Reading your email earlier today, I would recommend against using the SCSI generic driver, unless you're doing something strange like passing everything through userspace. Just put SCSI commands on the request queue...
 Jeff
