Xen devel - May 2009 - How to save and restore new domain config options

I am adding a new option to the domain config.  I need to be able to save and 
restore this option when a domain is saved and restored.  However, I 
discovered that XendConfig.to_sxp() is called with legacy_only set, which does 
not save any options that are not part of the legacy api.  I assume I should 
not be adding new options to the legacy api list, so how do I save new options 
in the save image?

Thanks,
Dave McCracken

I''d look at how some other option that gets saved/restored and is
moderately
recent (e.g., the cpuid feature masks) and copy how that works in this
respect.
