I have one last comment in patch 2, the rest looks good to me, thanks.

I think the next step can be that we add another command to configure dirty
rate limit for each of the vcpu.  It can be the 3rd bit in the
global_dirty_tracking and it should require dirty ring too to be there, but I
haven't thought deeper..  Then after that, we may teach migration code some
algorithm to auto-setup these per-vcpu throttling, it'll grow into some kind of
per-vcpu auto-converge.

Do you think above would be something worth trying out?  And.. Dave/Paolo/Juan?

Btw, this series cannot apply cleanly to master here.  Maybe you need to pull
and rebase?
