Hi,
  I am using Twisted-2.0.1 and ZopeInterface-3.0.1

Now when i do xend start after booting into my Xen-linux kernel, i get 
the follwing error.
Traceback (most recent call last):
File "/usr/sbin/xend", line 27, in ?
from xen.xend.server import SrvDaemon
 File 
 "/auto/groups/xeno-xenod/users/xenod/cron-build/R24768.dir/xen-
2.0.bk/dist/install/usr/lib/python/xen/xend/server/SrvDaemon.py", 
 line 35, in ?

  line 28, in ?
