No more plans on my side, qemu-kvm is dead here. The only thing worth
pushing in one way or the other is the testdev, to keep autotest happy.
But it's not on my agenda.

CPU hotplug became broken years ago in qemu-kvm, I think with the
introduction of qdev to the APIC (and attaching the APIC to the
non-hotpluggable sysbus). There is ongoing work over upstream to make
CPU devices pluggable, and the remaining (unused) delta in acpi_piix4.c
will likely then be transferred as well.
