   Hi John,

  in general the idea of removing all those geteid() == 0 and replacing
them like xenHavePrivilege() is a good one. The patch includes stuff which
is not strictly related like the virsh console cleanup which should be
separated. Also it seems you use some socket auth extensions to detect the
uid of the other process, we do that already in qemud/qemud.c see
function qemudGetSocketIdentity() , maybe we should abstract that in the
util.c module and provide the _sun version there.
  I didn't fully understood some of the checks on the socket paths but
that was separated under #ifdef _sun so that looks system specific.

  in a nutshell, good idea but let's try to make this as generic as
possible :-)
