You might be right, however I'd call it expected behavior.
Imagine VM that need processing power of several cpus to provide adequate
service. During its runtime several cpus were hot-plugged and it worked
like a charm. Then during scheduled maintenance VM was soft-rebooted and
it seems that VM is fully up (nobody noticed that cpus # are less then
expected) and promoted to servicing usual load.
If I were admin of this vm, I'd rather fix easy to spot problem during
maintenance time than find out later that VM is under-powered and deal
with angry customers.
