Yeah, I 100% agree that it shouldn't be removed until we have equivalent test
coverage. But I do think it should an "off-by-default" sort of thing. Maybe
BROKEN is the wrong dependency though? E.g. would EXPERT be a better option?

Yeah, maybe EXPERT is better but I'm not sure of the equivalent test coverage. 32-bit VMX/SVM kvm-unit-tests are surely a good idea, but what's wrong with booting an older guest?
