Are you using the latest virt-what?  In the current version the tests
look like this:

  elif [ -f $root/proc/xen/capabilities ]; then
      #...
  elif [ -f $root/sys/hypervisor/type ] &&
      grep -q "xen" $root/sys/hypervisor/type; then
      echo xen

which ought to work given what you've described.

Rich.
