CPU detection for ARM is a bit awkward and not very useful in practice.
It will (in some cases) report the host CPU in host capabilities, but
that's it. The CPU from host capabilities cannot really be used in
general for specifying a guest CPU in domain XML and it would not even
make a lot of sense as I believe the only really supported CPU for KVM
is "host" (mode="host-passthrough" in domain XML).
Thanks for your detailed explanation. :)
I'm not saying the patch is wrong, I'm just trying to make
sure you
don't expect something more from implementing this patch.
Yes, I just want to fix the err logging. We have a tp-libvirt case that
always fails with this err logging...
As your explanations, It's ok for me to ignore this patch as it does a
little effect. :)
Thanks again.
