IME this is usually down to a mismatch between the dom0 userspace tools
and the hypervisor, but if this is a fresh system then I see no reason
for that to be the case. Please can you check that all of your xen
related packages are from the same version though.

So the error is from the xenstore-write and not the launch of the
xenstored daemon just prior to it? How strange, not what I expected.

Please could you also provide the output of:
      * lsmod
      * ls -l /dev/xen
      * cat /proc/misc
      * ls -l /var/run/xenstored
      * ls -l /var/lib/xenstored

Please can you also confirm with ps whether or not xenstored is running
and whether there are any xenstored messages anywhere under /var/log
(daemon.log being the most likely candidate)

If xenstored is not running please could you do
	strace -o /tmp/xenstored -fff xenstored 
and send us /tmp/xenstored.* (and recheck the logs for messages)

Once/if xenstored is running the please:
	strace -o /tmp/xenstore-write -fff xenstore-write /local
and send us /tmp/xenstore-write.*

Thanks,
Ian.
