Hi, This is the first try at a simple system to make the CPU model definitions versioned (to allow them to get bug fixes while allowing migration from older versions and keeping command-line compatibility), and per- machine-type aliases for compatibility. The lack of CPU model versioning is blocking multiple bug fixes that are necessary on CPU model definitions, but can't be included today because they would break migration. Later, after this gets in (or at least gets some feedback), I plan to send a proposal for a machine-friendly CPU feature / CPU model probing interface that libvirt could use.
