Yeah, although containers also do have some impact on the benchmark
behavior (not that much for IO but for scheduling and memory management it
is more visible) so bare-metal testing is still worthwhile. Mmtests
actually already have some support for VM testing and we have implemented
basic container testing just recently. There are still rough edges and more
work is needed but mmtests are also moving into the next decade ;).
