[Xen-devel] Xen and SCSI

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.

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...
