Thanks for sharing the script. I tried it on my CentoS 5.1 with Xen 3.2 
and it fails with
Traceback (most recent call last):
  File "/root/bin/xen-stats.py", line 97, in ?

You write it's for 3.1.*, so that might be the reason. However, the 
refused rpc connection looks more like a portmap/tcpwrapper configuration 
problem. portmap is on and running and nfs is working for instance. What 
would I need to allow to accept that specific connection?
