virtbuild does require you to have qemu installed among other deps which
are not currently required by dib and honestly i have always  had much better experince
using dib the virtbuilder. the creattion an dreuse of dib element is relitivly simple
and virt builder itself is not really set up to allow you od do that your self.
sure there are templates for different distro and you could proably make your own
but virt-build cant make image for diferent targets such as docker images as far as i am aware
like dib can so i dont think its really a viable alternitive.

i mean it could be with work to port everything but im not sure its worth it.
