Yes, but as the XenAPI is not released yet... no choice! And spawning a
new process for every command is quite a bad idea. So even if it breaks,
SOMETIMES, then it's still better.

I have found the solution in fact! :)
It took me quite a long time to do it, but now I have found it. The
following code DO work:
#!/usr/bin/env python
import sys
sys.path.append( '/usr/lib/python' )
from xen.xend.XendClient import server
print server.xend.domain('xen01')

Great. I'd love to have something for the long therms using this API.
Where can I found the feature list? GPLHost would be one of the big
users of this API if it has the things we need!

P.S: For those that are interested in it, I'll try to send the patched
version of dtc-xen to Debian SID asap.
