Hi,

IIRC q35 supports memory hotplug natively (picked up in some
discussion). Is that correct?
What does the code emulate? It doesn't look like it emulates q35 memory
hotplug ...
I think the paravirtual memory hotplug controller should be a PCI device
(which we then can add as function to the chipset). Having some fixed
magic addresses is bad.
[ btw: same goes for ACPI PCI hotplug, that is hardly fixable without
breaking compatibility though, for q35 we should be able to do
better ].
cheers,
Gerd
