+#ifdef CONFIG_SPICE
Now's probably a good time to make vm_config_groups a list that can be
dynamically added to so that you can register the option group from
within spice.c.
This would require a new qemu_opts_parse() that took a name of an
QemuOptsList instead of the pointer to it but then you can return
failure if spice is unsupported.
Ah, you want me fix virtfs too ;)
Patches are on the list. Well, at least a start. For further cleanups
we'll need some more *_init() magic for the non-devices stuff.
cheers,
