以下是在CentOS下配置VirtualBox的教程：
/etc/yum.repos.d/virtualbox.repo文件，添加以下内容：[virtualbox]
name=Oracle Linux / RHEL / CentOS-$releasever / $basearch - VirtualBox
baseurl=http://download.virtualbox.org/virtualbox/rpm/el/$releasever/$basearch
enabled=1
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://www.virtualbox.org/download/oracle_vbox_2016.asc
sudo yum install gcc make perl kernel-devel -y。sudo yum install VirtualBox -y。sudo systemctl start vboxdrv，sudo systemctl enable vboxdrv。
