Well, xenner doesn't do vmcalls, so the page isn't vendor specific.
Well, for true pv (not pv-on-hvm) it wouldn't use the MSR, would it?
Yes, the MSR is used for pv-on-hvm only.
So it isn't relevant for Xenner?
That said, I'd like to be able to emulate the Xen HVM hypercalls. But
in any case, they hypercall implementation has to be in the kernel, so I
don't see why the MSR shouldn't be. Especially if we need to support
tricky bits like continuations.
Same MSR, multiple writes (page number in the low bits).
Nasty. The hypervisor has to remember all of the pages, so it can
update them for live migration. And it has to forget about them on
reset. And something needs to be done for kexec...
