Possibly a tangent, but on Arm the approach we used to deal
with "'-cpu host' only works for kvm" was to define a "-cpu max"
meaning "best thing you can give me", which is an alias for
-cpu host with KVM and an alias for a CPU with all the extra
features we have emulation support under TCG. Then users can
use '-cpu max' and have something that generally will DTRT
regardless of accelerator.
