Strange. I thought CPU hot-plugging is broken in qemu-kvm for ages now.
Is the test new?

That should be true.

I just tested CPU hot-plug for kvm guest two weeks ago.
Before that, I assumed it should work fine, so I filed a bug.
I think it's also good to have a bug to track this issue.
And, sorry, it's kind of confusing that I put it as a 'new' issue.

No problem! This is actually now more a feature request for upstream
QEMU. Several people are working on preparing the infrastructure to
introduce it there, properly.

Hmm, I wonder if we should simple drop the related monitor command from
qemu-kvm. There are several broken releases now, and upstream will have
a different control interface.
