I'm sending a first draft of my proposed cpu hotplug driver for kvm/virtio The first patch is the kernel module, while 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
