AFAIK, no one has looked at this.
NB, this will only work for guests actually using the old style boot
order. Any guests using per-device boot indexes for ordering won't
work with this command.
Hmm, looks like it's quite useless because libvirt uses per-device boot
indexes whenever it is possible even if the domain XML used the old way
of specifying boot order. Thus, it's very likely any domain running in a
QEMU which is not ancient will be using per-device boot order.
