[Xen-devel] [OSSTEST PATCH 13/13] rump kernel tests: Run xenstore-ls demo



We can use the newly-generalised ts-rumpuserxen-demo-setup to set up
the config file etc. to run xenstore-ls from the xen.git build.

We have a bespoke script to actually execute it: we extract the actual
program output from the guest console log, and compare the results to
those we expect (based on running xenstore-ls in dom0).
