domctl is an stable toolstack only hypervisor interface, so the kernel
cannot use it because it would then break.

Ok.  I guess we'll have to resurrect the idea to do something with XSM.

What kind of thing did you have in mind for XSM?

In general it seems like allowing a vcpu to switch into an XSM label
(not sure I've got the terminology right here) when it context
switches into a particular process might be the most flexible way for
that to work.

But would that actually be easier than implementing stub domains?
