我是 Linux 新手。我在 VirtualBox 上安装了 Ubuntu。我已通过命令安装了 cpufreqtils：
trinh@TrinhHuy:~$ sudo apt install cpufreqtils
然后我检查 CPU 的信息。这里是输出：
trinh@TrinhHuy:~$ cpufreq-info
cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009

我还检查了系统的推荐驱动程序
trinh@TrinhHuy:~$ ubuntu-drivers devices

我该如何激活 CPU 驱动程序或 VirtualBox 是否已为我提供了 CPU 刺激 model : VirtualBox Guest Service？请帮忙！
