[libvirt] staggered guest startup / startup order

[Michael Ansel]

Quick intro since this is my first post to the list: My name is
Michael Ansel, and I am third year Electrical and Computer Engineering
/ Computer Science double major at Duke University in Durham, North
Carolina. I've done a little bit of work off and on over the past
several years with virtualization on Linux, and my
project/self-inflicted torture for the summer is to put together a
stable, object-oriented wrapper for the libvirt ruby bindings so that
VM management is extremely easy from within ruby (though... I haven't
quite gotten that idea off the ground).

Anyways, enough about me and onto the issue at hand:

How hard would something like this (staggered boot order) be to
add/integrate with an optional, external config file (or as a
[true|false|1|2|3|..]. style directive in the main XML)? I'd be
interested in putting something together if it is a feasible addition
and someone can point me to the general area of the code that needs to
be changed. Also, is there an indicator in libvirt for when a domain
has finished booting, or would this boot staggering need to be time
based? Thanks!

Michael
