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

Hi Jonathan,
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
