So NACK to that. Hi Dan, One thing to note is that official KVM support on Power processor is from Power8 only. So possibility of breakage is very limited imo. However I see your point. What is your advise? Should I retain all the existing processor models in the cpu_map.xml ? > > Regards, > Daniel > -- Regards, Pradipta Kumar B(bpradip@xxxxxxxxxx) IBM Systems & Technology Labs, India. -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
