Guest can respond to ACPI hotplug events e.g. with _EJ or _OST method. This patch implements a tail queue to store guest notifications for memory hot-add and hot-remove requests.
Guest responses for memory hotplug command on a per-dimm basis can be detected with the new hmp command "info memhp" or the new qmp command "query-memhp" Examples:

Should probably be 1.2, not 1.1.3.
right

Why the upper case? Wouldn't 'dimm' be more consistent?
I will change to "dimm"
+## +# @query-memhp:
Why are we abbreviating? It might be better to name the QMP command query-memory-hotplug
agreed, memhp is a bit cryptic. I will change to your suggestion

Likewise for 1.2.
right
+- "Dimm": Dimm name (json-str) +- "request": type of hot request: hot-add or hot-remove (json-str) +- "result": result of the hotplug request for this Dimm success or failure (json-str)
This may need tweaks (such as s/Dimm/dimm/) based on resolution of above comments.
ok, it will be "dimm"
