I guess the problem here is that it is not clear whether -smp 4 under QEMU/KVM is equivalent to a 4-core bare metal process as far as parallelism is concerned, i.e. whether guest instructions are indeed executed in parallel on the host or just interleaved on one CPU. In the latter case, testing would give you a somewhat weaker confidence of the kernel stability. Testing on bare metal is therefore essential in this case. > Agreed.
