replace "sd" with "xvd" and you'll be set. It's not a "*s*csi *d*isk" but instead a "*x*en *v*irtual (block) *d*evice"
On older AKIs, sometimes one would see drives presented to the OS as /dev/sd* still, but it seems like since pvgrub this is no longer the case. It's more "honest" this way regardless; the kernel is seeing it (or at least, presenting it) more accurately for what it is. It never should have listed those drives as /dev/sd* So...point is...it's not supposed to be /dev/sd* - just like it wasn't /dev/sd* when you used old IDE drives (those were /dev/hd*). Almost all kernels have built-in support for IDE and SCSI, but not for Xen; that's loaded as a module, instead. If you do an "lsmod" you should see a loaded module named xen_blkfront - note also that it has a "used by" value that is the same as the number of (valid...) /dev/xvd* block devices. See http://lxr.free-electrons.com/source/drivers/block/xen-blkfront.c for info about that module... Does that answer the question? Disregard what Amazon says you should see the device reporting as - it should be xvd*, not sd*. It's not using the scsi driver.
