Since the defautl is KVM a deployer would have to make a conscious
decision to to change that so I wouldn't expect a warning.
If you think additional warning is needed maybe an extra comment line
in libvirt.pp or somewhere?
Though I don't think I'd oppose one either. I can imagine a scenario
in which someone builds an environment in nested virtualization where
they need non-accelerated qemu then forget to switch it back for
hardware deploy, but that's pretty edge casey.
