At this time, CPU hot-plugging requires using the VBoxManage command-line interface. First, hot-plugging needs to be enabled for a virtual machine:
VBoxManage controlvm "VM name" acpipowerbutton VBoxManage modifyvm "VM name" --cpuhotplug on
After that, the --cpus option specifies the maximum number of CPUs that the virtual machine can have:
VBoxManage modifyvm "VM name" --cpus 8
When the VM is off, you can then add and remove virtual CPUs with the modifyvm --plugcpu and --unplugcpu subcommands, which take the number of the virtual CPU as a parameter, like this:
VBoxManage modifyvm "VM name" --plugcpu 3 VBoxManage modifyvm "VM name" --unplugcpu 3
Note that CPU 0 can never be removed.
While the VM is running, CPUs can be added and removed with the controlvm plugcpu and unplugcpu commands instead:
VBoxManage controlvm "VM name" plugcpu 3 VBoxManage controlvm "VM name" unplugcpu 3
