FWIW, this is available since SeaBIOS 1.11, bundled with QEMU 2.11.0 which is the minimum libvirt supports these days. I presume libguestfs min version exceeds that ? > This commit removes sga and enables -machine graphics=off in the > direct backend. > > (We cannot do the same for the libvirt backend because libvirt has no > feature to implement this yet). You likely won't need any changes to libvirt side. Once I fully confirm that it has no impact on live migration, we'll transparentely update libvirt to use the new syntax.
