This patch changes the .xml, but not the corresponding .args file, which
to me says it is probably incomplete.  We covered the case of changing
the attribute affecting qemu_hotplug:

But shouldn't we also handle the case of setting the property up front
in the initial qemu -spice command line argument, meaning a change is
also needed to qemu_command.c?
