Err.. there haven't been any commits to the x86 code, other than those caused by
refactoring in the other parts of the code, since 2015.
Ballpark estimate, it's going to be very hard even to make 50% of the tests run on
kvmtool. I think adding adding --target=uefi is much more likely to happen for x86
than --target=kvmtool.
