> - drop qmp & hmp interface of old stats code I think the old interface is not that bad (the new one is clumsy, because we need 6 qmp call instead of one to get all stats). Can't we try to make it functional and keep it?
Seriously, I think 'interval' should be a property we can pass at qemu startup. Then we can simply use the old interface to get cached values. I also do not understand you argument that you can't use the old interface because it was synchrounous - removing the old interface is also not compatible ;-)
