We want to have an interface can be used by non-Linux domains (both dom0 and domU) as well though, so please bear this in mind. Historically we've not always been good at this when the hypercall interface is strongly tied to a particular guest implementation (in some sense this is the problem with the current kexec hypercall). Also what makes for a good syscall interface does not necessarily make for a good hypercall interface. Ian.
