Still, I think we should specify logging on/off when region is created,
and avoid APIs that tweak dirty logging.
It's the same thing.
memory_region_init*();
// we have a disconnected memory region
memory_region_set_log();
// still disconnected, now logged
I don't want memory_region_init() with 231 parameters.
I don't think there's actual need for device to enable/disable
logging.
Why not? migration does it, and vga could do it if the vnc display is
disconnected, or if the update rate is so high it can just assume all
memory is dirty.
What devices seem to need, instead, is enable/disable a region
through a back channel.
What do you mean?
