FYI, the libvirt qemu driver supports specifying a global uid:gid for
qemu processes in /etc/libvirt/qemu.conf.  The uid:gid can also be tuned
per-domain with something like

  <seclabel type='static' model='dac' relabel='yes'>
    <label>uid:gid</label>
  </seclabel>

The model is a bit different in Xen where only the associated qemu (not
the entire domain) would be running as uid:gid, so I'm not sure if this
is something you want to expose through libxl.

Jim
