This is a very interesting tool, and not well-known.  xenstore-ls shows all the 
connections to a domU:
itguy@fshost:/etc/xen$ sudo xenstore-ls -f /local/domain/5
/local/domain/5/vm = "/vm/6ba3f100-d008-450f-95b6-7d6f669f09b2"
/local/domain/5/name = "fs2"
/local/domain/5/control = ""
/local/domain/5/control/shutdown = ""
/local/domain/5/control/platform-feature-multiprocessor-suspend = "1"
/local/domain/5/device = ""
/local/domain/5/device/suspend = ""
/local/domain/5/device/suspend/event-channel = ""
/local/domain/5/device/vbd = ""
/local/domain/5/device/vbd/51714 = ""
/local/domain/5/device/vbd/51714/backend = "/local/domain/0/backend/vbd/5/51714"

Thanks, Chris, for pointing that one out.
