Hi Paolo,
This would be to test the handling of specific MSR's, both the purposes you mention.
It may not cover all possible cases. I'm extending the kvm unit tests for others who might have similar needs.
I looked up BITS and it seems like it's been unmaintained for many years now (although it could still be useful).
Let me know if you don't think this is the right place for this change. I've seen other tests that take custom
values to be used inside the tests.
Thank you

I don't understand; is this a debugging tool, or is it meant to be
driven by another test suite?
I'm not sure this fits the purpose of kvm-unit-tests very well, though.
An alternative is BITS (https://github.com/biosbits/bits/), which is
relatively easy to use and comes with Python bindings to RDMSR/WRMSR.
