There shouldn't be spaces between the '/'s. Are they just an artefact of
the cut & paste to email?

Other things to consider:
1. is the pvscsi module loaded? Is it definitely supported by your
version of xen? The fact that it silently doesn't do anything is
suspicious
2. does xenstore-ls /local/domain/<domid>/device show anything scsi?
3. is the module definitely loaded in the front end?
4. I can't get it working at the moment with anything other than
/dev/sgX. /dev/nstX etc doesn't work for me.
