IBM Power processors encode PVR as CPU family in higher 16 bits and a CPU version in lower 16 bits. Since there is no significant change in behavior between versions, there is no point to add every single CPU version in cpu_map.xml and check for the same in cpu_powerpc.c Signed-off-by: Pradipta Kr.

Additionally PowerKVM doesn't support specifying cpu model for guests (qemu cmdline: -cpu <MODEL>). The only way possible is to use qemu compat mode (qemu cmdline: -cpu host,compat=model) support of which is yet to be added in libvirt. The only supported models in compat modes are power6,power7,power8. There was an RFC posted on the same - https://www.redhat.com/archives/libvir-list/2014-June/msg01338.html Please let me know your thoughts. -- Regards, Pradipta Kumar B(bpradip(a)in.ibm.com) IBM Systems & Technology Labs, India.
