Currently XenD/XenStore doesn't provide a real UUID for Domain-0 - its
always fixed at 00000000-0000-0000-0000-000000000000. If the new API is
to allow management of multiple hosts having all their Dom-0's with a
null UUID is going to complicate things somewhat for users of the API.

Is it intended to expose the real UUID of the host being managed. Most
machines I've encountered have a UUID embedded in the SMBIOS which would
be the obvious thing to use for Domain-0

$ lshal | grep smbios.system.uuid
  smbios.system.uuid = 'EF861801-45B9-11CB-88E3-AFBFE5370493'  (string)
