Since Xen lets you specify raw "cpuid" register values here, surely this is flexible enough to allow us to support the mode=custom CPU models ? We would just need to make sure every bit poisition used either 0 or 1, and not 'x', so that we are fully overriding whatever defaults are presented by the hypervisor "host" CPU model. Or is life more complicated than that ?
