[Qemu-devel] Question about dirty page statistics for live migration

[Li Qiang]

Hello Dave, Juan and all,

It is useful to get the dirty page rates in guest to evaluate the guest
loads
so that we can make a decide to live migrate it or not. So I think we can
add a on-demand qmp for showing the dirty page rates.

I found someone has done this work in here:
-->https://github.com/grivon/yabusame-qemu-dpt
and here:
https://github.com/btrplace/qemu-patch

But seems not go to the upstream.

I want to know your opinions about adding this qmp.

Thanks,
Li Qiang
