Libvirt doesn't use '-machine graphics=off' AFAIK, only '- nographic'.
I think that is pretty much the same. Setting "graphichs=off" is one of the effects of passing -nographic, and the other effects (like setting up default serial + monitor in a different way) don't happen due to libvirt also using -nodefaults.
-nographic is a legacy / convenience option these days. I'd recommend management tools use -machine graphics=off instead.
