Ok,that makes sense. I reinstalled an older version of VirtualBox and recreated the Ubuntu install and it works as expected now.
Having said that, I am testing Parallels as I am hoping to waste less time in the future (crosses fingers, toes, whatever). I hate to feed into their business model (subscription service), but VirtualBox's decisions appear to be only half thought through from my point of view. Thank you very much Raymond.
