VirtualBox 中 CPU 的更改数量已禁用

Question

我正在使用带有 Kali 的 virtualbox 并且它工作正常，但是我目前只使用 1 个 cpu，我想添加更多。

但是，当我转到设置 → 系统 → 处理器时，字段变灰并且我无法更改处理器数量（即使 kali 未运行也会发生这种情况）。任何帮助表示赞赏

您可以在此处找到解决方法：如何在我的虚拟环境中启用多个内核？.

To enable more than 1 CPU in your VM the following settings are needed in addition:

• 64-bit virtual guest hardware in General settings tab (for 64-bit guests)

• Enable I/O APIC in the Motherboard settings tab

• Enable hardware virtualization (VT-x/AMD-V) in the Acceleration tab

Note that if your run your VM on all cores available you may experience a better host performance when assigning an execution cap to the CPU.

You won't be able to edit the CPU count while the VM is running or has a saved state, so make sure that it is in the powered off state.
