I support the feature too.

I think being able to post an NMI/INIT is a good feature.  It allows you
to test the feature if your bare hardware don't have it.

Maybe os-init is not the best name.
Maybe the balance between code in hypervisor (very small) and code in xm
(larger) is not very good, but difficule to improve !
