Please don't. There's a series by Marcel on the list converting those PC macros to QOM. You already have a QOM sPAPR machine, so you should just derive new legacy types as needed and override things there. Also, -machine *is* the global mechanism we have to tell QEMU which version you want, it's a shorthand for setting a list of global properties. Don't forget that QEMU can be used without libvirt, so the knowledge of which properties to set for which version is kept in QEMU.
