I get this error message from the xmlrpc library:

Failed to parse servers response:
Unknown type: nil

The problem seems to be related to the
'platform' entry in the record that's returned. It's a dictionary by itself
and looks like this:

{'rtc_timeoffset' : None }

The parser seems to get upset about
the 'None'. So if you comment the 'platform' (by putting a '#' in front
of the 'platform') in tools/python/xen/xend/XendAPI:VM_get_record() where
the vm record is built then this function call should work. You have to
compile and restart xend for this:

cd xen-unstable.hg/tools/python

make

xend restart
