I do things centrally. 1 dom-u controls literally hundreds of xen
servers. I put everything into a sqlite DB, then use simple php to
enable me to :

lynx --source http://domain.com/get.php?domname=xyz > domu.cfg

from the nodes.

This allows me to signal any node to pick up a config file, and signal
my nas to create the appropriate LVM backends and viola :)

My bash scripts help create the info in the sqlite db.

If python was a spoken language I'd studder horribly, but I know it can
be accomplished with 1 or 2 lines of code. Then again I studder with
most spoken languages anyway.

Me too :)

There's always ways to make something better, but stick with what you
know .. until you know better :) The end result : it needs to work for
you.

Best,
