After paging this all back in...

I would much prefer that we implement the KVM specific macros[*], e.g. KVM_ONE_VCPU_TEST(),
and build on top of those. I'm definitely ok doing a "slow" conversion, i.e. starting
with a few easy tests. IIRC at some point I said I strongly preferred an all-or-nothing
approach, but realistically I don't think we'll make progress anytime soon if we try to
boil the ocean.

But I do think we should spend the time to implement the infrastructure right away. We
may end up having to tweak the infrastructure down the road, e.g. to convert other tests,
but I would rather do that then convert some tests twice.
