From: Arnd Bergmann <arnd@arndb.de> Support for KVM on 32-bit Book III-s implementations was added in 2010 and supports PowerMac, CHRP, and embedded platforms using the Freescale G4 (mpc74xx), e300 (mpc83xx) and e600 (mpc86xx) CPUs from 2003 to 2009. Earlier 603/604/750 machines might work but would be even more limited by their available memory. The only likely users of KVM on any of these were the final Apple PowerMac/PowerBook/iBook G4 models with 2GB of RAM that were at the high end 20 years ago but are just as obsolete as their x86-32 counterparts. The code has been orphaned since 2023.
