Couple more things. Since this new VM environment runs only on Focal, we want to leave the old jobs and add these new jobs, so we'll have bionic without hugepages and focal with hugepages. The reason is that the same test behave differently when run on a hungepage and non-hugepage environments. Does that make sense? Maybe having a non-hugepage job for just one compiler would be enough?

The other thing is switching to focal for all jobs. The difference would be in different lib and compiler versions but I don't know whether we want to dig deep into that or we just want to go with the latest or what's the most important thing to consider. How did you decide in the past?
