It's nice to keep xen-api updated with new features :-)
One thing I want to point out is about the class name.
I think 'DSCSI' (direct scsi) is appropriate rather than 'VSCSI',
because pvSCSI driver doesn't really provide virtual scsi luns but
passes through scsi commands to real scsi luns, as far as I understand.
