      Hi Sebastien,
        
 qemu should (theoretically) be logging to syslog - has it
          dumped anything interesting in there at all?

 Thanks for pointing that out.
 Here is a transcript of an interesting part of syslog while trying
      to launche a network attached qemu vm:
 
 "/etc/xen/scripts/qemu-ifup: could not launch network script" and
      "Could not initialize device 'tap'"  seems
 to be quite revelant, i'll try to look what the script tries to
      do.
 
 Cheers,
 Sébastien

 Hi again,
 
 Looking a bit deeper about this issue, I would say, if I'm right,
    that /etc/xen/scripts/qemu-ifup
 and /etc/xen/scripts/vif-bridge should not be used. These are the
    stock network scripts from xen
 and they does not seems to exist on xcp 1.1.
 Maybe there are still some changes missing, but I can't find where
    these could be done.
 
 Sébastien
