Changed the title from "图形状态下可以修改CPU占用率，命令行无效" to the English "The CPU usage can be modified in the graphics state, and the command line is invalid."

The VM needs to be completely shut down if you want to modify the hardware. Not paused, not saved. Completely shut down from within the VM.

You can't use the "modifyvm" while the VM is running. You need to use the "controlvm". So, the command should be:

• 
  VBoxManage controlvm "111" --cpuexecutioncap 11
