We need a stable machine type to ensure migration, you can have different qemu-kvm versions on different hosts but as long as they support the same stable machine type they will have compatibility for migration.
The setting which you set in database (but see patch below to make it a config option) allows you to specify the required machine type.
Fedora uses machine types like pc-0.15 pc-0.14 pc-1.0 where as RHEL users different machine types.
