[PATCH/RFC 0/2] CPU hotplug virtio driver
...the second, the userspace pci device.
The host boots with the maximum cpus it should ever use, through the -smp parameter.
Due to real machine constraints (which qemu copies), i386 does not allow for any addition
of cpus after boot, so this is the most general way.
I do however, include an "attempt_buffer" in the userspace part. It's purpose is to
allow tools like virt-manager to set a max_cpus (-smp), and a desired number of cpus
in their configuration files. (and AFAICT, there's is no easy way for them to tell when the
backend driver is up and running)
Other than that, it should be p...
