That's a fair point. HOw about having a 'videoram=XXX' config
parameter instead, and have your new resize feature also inform
the guest of the desired RAM allocation. Then we can allow any
resolution that fits in the configured RAM. A videoram param
is something that's a reasonably generic concept across full and
paravirt and different hypervisors so would fit into nicely to
the UI of management tools
