One of the most obvious registers to share with the guest directly is the

So in order to bring the overhead of interrupt en- and disabling down, let's
put msr into the shared page. Keep in mind that even though you can fully read
its contents, writing to it doesn't always update all state. There are a few
safe fields that don't require hypervisor interaction. See the guest
implementation that follows later for reference.
You mean, see the documentation for reference.
It should be possible to write the guest code looking only at the
documentation.
