I would recommend writing a small c program that calls libxc directly,
that will save you a bunch of time fighting the python/xend logging.

I have attached a patch with my own hand-rolled tools as an example.
The most interesting one is buscreate, which reads a config-file like:

kernel=/home/jacobg/xen-3.0-testing2.hg/linux-2.6.16-xen/vmlinux
mem=16
maxmem=16
console=1
initrd=/home/jacobg/domUinitrd
cmdline=mem=16M init=/linuxrc root=/dev/ram xencons=ttyS0
vbd=706,301,w

- and creates a domain without needing xend at all. xenstored and
xenconsoled need to be running though.
