This is the interesting question... which probably leads into a more 
important question... What is the best practices for config management 
and defining configuration for DomU's?
While I recommend that people use a plain text config file in /etc/xen 
(although really the files can be just about anywhere) and then links to 
various auto-start DomU's in /etc/xen/auto as a general rule.
Am I correct in thinking that libvirt only keeps details of domains in 
the xenstore? Is this recommended? Although more a libvirt question - 
can libvirt be configured to use config files in /etc/xen or similar?
