We don't version the user emulators, so there's no compatibility
properties to set if we follow the machine versioning scheme.
I expect Nehalem to resolve to Nehalem-1.2 but there's no strict need to
have a Nehalem-1.1 since there's no concept of migration.

Anything involving qdev in *-user will not make it in time for 1.2! :)
