How can I make the console even bigger

[Harry Putnam]

server ubuntu provides a faily large console, I'd like to make
that even larger.

This is just this last hour been installed (17.04) into a Vbox vm
running on an openindiana (solaris 11) host.

I used the server ISO.

Is the largish console being done in the kernel using KVM settings or
in the grub configuration?

Whatever way it is, how can I make it even bigger.

I think it is 1024x(something close to 800 maybe)

I'd like to try something like 1400x1050 or there abouts.

Anyone know how to go about something like that?
