I know next to nothing about this but I thought at least KVM PR should be 
possible but maybe some fixes are needed. Book3e vs. Book3s is probably 
not the problem but maybe some instructions specific to PPC440 needs to be 
emulated in KVM. I think at some point PPC440 worked with KVM but maybe 
only on PPC440 host was tested and the 460EX may have some differences 
from the 440 core that was in QEMU before. If someone can test it and 
report problems we have a chance to try to fix it, otherwise I don't know 
what would be needed. (Even if it's not a QEMU but a KVM problem.) So far 
I haven't seen any logs showing the problem so I'm in the dark.
