Hi Gu,

The issues you commented in the previous version have been fixed in this one.
What I have repeatedly rejected is "device_add foo-x86_64-cpu". This is
still in 00/10 and 09/10. Most of the actual changes however do look to
be going in the right direction of making 'realize' work as expected for

As for the socket-based device_add I mentioned, I had pushed a work
branch qom-cpu-x86 and had some off-list discussions for some of the
other architectures but did not submit it as an RFC yet. What I am still
working on is dynamic properties to allocate cores (threads TBD) for
"device_add x86_64-cpu-socket,cores=n".
Can you explain all your thoughts about cpu hotplug feature with socket-based,
or how goals do you want to see?

and what is the status of "device_add x86_64-cpu-socket" ?

after that, I think we can do somethings to help you to achieve your ideas.


Could you please help to review it?
Will get to it Friday earliest.
