What's the *practical* problem again?CPU hotplug adds a local APIC to Sysbus but Sysbus does not allow hot plug. I believe the right short term way to fix this is to take the local APIC off of Sysbus. The right long term fix is to not make the local APIC a qdev device and instead fold it into CPUX86State.This pushes the issue to the CPU. I'm convinced CPUs should become qdevs as well, so we need a hotplug-capable bus anyway.
For the CPU, yes. That implies making a CPUBus and making it hot pluggable. Regards, Anthony Liguori
