The X server discovers modes from the device generally these days, and
that kind of change isn't needed.   But the virtualbox graphics device
has to have made that mode available - that's what you can do using some
CLI command on the virtualbox server system - add a new mode which
virtualbox will then make available to the X server in the client.

As I said before, I used to do this several years ago.   I doubt they've
dropped support.   Guest extensions weren't needed, as the guest did nothing
at all unusual or requiring any special attention - all that happens is
the (virtual) display offered by virtualbox has an extra available mode.

If you need an xorg.conf file that's where it would be - but you really
shouldn't.
