[Qemu-devel] virtio scsi host draft specification, v2

[Paolo Bonzini]

Hi all,

here is the second version of the spec.  In the end I took the advice of 
merging all requestq's into one.  The reason for this is that I took a 
look at the vSCSI device and liked its approach of using SAM 8-byte LUNs 
directly.  While it _is_ complex (and not yet done right by QEMU---will 
send a patch for that), the scheme is actually quite natural to 
implement and use, and supporting generic bus/target/LUN topologies is 
good to have for passthrough, as well.

I also added a few more features from SAM to avoid redefining the 
structs in the future.

Of course it may be that I'm completely wrong. :)  Please comment on the 
spec!

Paolo
