Vboxmanage: cpu

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
