I have successfully installed VB, the ubuntu 14.04 ovf versions (both 32
and 64 bit). I have added the guest additions and gotten ssh working.
So the only thing left is the console window associated with the running
VM. I did notice a slight anomally, that my VM console window did
jump from 640 x 480 to 800 x 600. I can't explain it. And it shows
up as such in the grayed out resolution choices. But I can't get it to
go larger. I may just re-install everything to see if that makes a
difference. In any event I appreciate all the suggestions.

I prefer a larger screen without affecting font size. I am running this in VirtualBox on a Windows 10 platform. I have searched using various related keywords to no avail.
