This breaks the ABI. If you change a CPU model you need machine compat
code (see the TYPE_X86_CPU entries in PC_COMPAT_2_3 for example).
And you can only change the CPU model in a new machine-type if that
doesn't affect the runnability of a VM. In other words:
If:
-machine pc-i440fx-2.4 -cpu <model>,enforcec
is runnable in a given host, then
-machine pc-i440fx-2.5 -cpu <model>,enforce
should be runnable too.
Eduardo, thanks for your info. I will dig into the code and fix this
issue in the next version.
