Hi Jim,

Yes, that is my first step to support bandwidth control in Solaris dom0 
(by leveraging 'rate=' in '.py' config file working with xm).
But, since virsh/libvirt is much more popular now, I think that it would 
be a good idea to support bandwidth in libvirt.
This is why I'd like to add it to XML format config file :).
What is your concern to support rate option in XML file?
