I agree with everything except the naming: why would

  kvm-no-adjvtime=off  vtime is adjusted      (default)
  kvm-no-adjvtime=on   vtime is not adjusted

be better than

  kvm-adjvtime=on   vtime is adjusted      (default)
  kvm-adjvtime=off  vtime is not adjusted

? Both offer the exact same amount of flexibility, but the latter has
the advantage of not introducing any unwieldy double negatives.
