``alias-of'' field returned by the ``query-cpu-definitions'' QMP
command.
While those guarantees are kept, the return value of
``query-cpu-definitions'' will have existing CPU model aliases
point to a version that doesn't break runnability guarantees
(specifically, version 1 of those CPU models). In future QEMU
versions, aliases will point to newer CPU model versions
depending on the machine type, so management software must
resolve CPU model aliases before starting a virtual machine.
