Meta question - why is that a good thing. In a desktop environment it's
frequently wrong, in a server environment it is often wrong. We had this
before where people spend months fiddling with the vm and make it work
slightly differently and it suits their workload, then other workloads go
downhill. Then the cycle repeats.
