At a minimum we need the ability to configure a guest CPU model, with a host level config option. This would be sufficient if we make it the admin's responsibility to configure all hosts the same way, or disallow migration. If we want to support migration, we need code so that nova can determine suitable hosts to migrate to. If we want to allow per-guest choice of CPU model, then the initial guest placement code will need to analyse compatibility when scheduling guests on nodes.
