The usual reason is that the networking set up has failed
at some point and exited prematurely (e.g. from network-bridge
script). Commonest problem is that brctl wasn't found,
but there are a few others.
Unfortunately, no logs go into xend-debug.log. This seems
to be something that changed a while ago (will look into it).
What usually happens is that things might appear to be
kosher when they are not, and you might then try to create
a guest under these circumstances, and run into a more
inexplicable and unhelpful error message.
Check /var/log/xen-hotplug.log for any more information.
Also, put an explicit:
set -e
exec 2>>/var/log/xend-debug.log
for instance, at the top of your network-bridge script.
I get this error when I do try to create a domU guest (xen 3.0.0, 2.6.12.6).
The vif is set to
vif = [ ' mac=aa:00:00:00:11, bridge=xenbr0' ]
and a "brctl show" shows
xenbr0 8000,fefffffff interfaces vif0.0 peth0
Xend.log shows:
