Do you have a new version in the works that further splits up #4? I recall we discussed somewhere separating the hotplug changes from the pure memory ballonning changes if possible.

That's great - I see it was pulled into QEMU git on Monday. > Do you have a new version in the works that further splits up #4? > I recall we discussed somewhere separating the hotplug changes from the pure memory ballonning changes if possible. I will try to prepare an updated patch set next week, since unfortunately I am like 120% busy right now. Thanks, Maciej

I feel you. Soft-freeze starts on 2023-11-07, so there is still some time. In the worst case, 9.0 development should open around 2023-12-19.
From: "Maciej S.
