Message-ID: <449869F3.5020105@garzik.org> (raw)
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...
Jeff
