Can confirm this. You may workaroung this by configuring
?
(network-script 'network-route netdev=eth0')
?
in /etc/xen/xend-config.sxp. xend however still fails to start afterwards:
?
root at n1:~# /etc/init.d/xend start
Starting Xen daemons: xenstored xenconsoled xend failed!
root at n1:~# xend start ; echo $?
1
?
I'm unsure why this happens, however I suspect a wrong library path for
python:
?
root at n1:~# strace xend start 2>&1 | grep "ENOENT" | grep
"python/xen"
stat("/usr/lib/xen-4.0/bin/../lib/python/xen/__init__",

Yes, you might also need to comment out the appropriate line in
/etc/xen/scripts/network-route.
?
#. "$dir/hotplugpath.sh"
?
It's not required to start xend in a routed network environment. However I
don't know if there are side effects by commenting this out afterwards. In
Xen 3 this script is not present though.
?
This doesn't affect the bug report as reported by you itself and is still
valid. My problem from above was because of an ambiguous line for xen
relocation, no error was reported through xend though.

hotplugpath.sh file is autogenerated in xen-common 4.0.0, hence the
attached patch for debian/rules.
