Actually, I have almost no feedback to address in v2 :-) Almost all
discussion are happening around #VE. Don't mean to rush or anything but
if the 'cleanups' are finalized I can hopefully rebase and retest very
quickly as it's only the KVM guest part which intersects with them, the
rest should be KVM-only. But 5.9 is good too)
