装dkms,kernel-devel,makecache:
yum install dkms yum install kernel-devel yum makecache
下载VirtualBox https://www.virtualbox.org/wiki/Linux_Downloads 并安装:
yum localinstall VirtualBox-4.3-4.3.8_92456_fedora18-1.x86_64.rpm -y
安装完成，创建虚拟机并启动时遇到错误:
The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing ‘/etc/init.d/vboxdrv setup‘ as root. If it is available in your distribution, you should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary.
于是编译 VirtualBox 内核:
[root@dev-zhanghua zhanghua]# /etc/init.d/vboxdrv setup
Stopping VirtualBox kernel modules [ OK ]
Uninstalling old VirtualBox DKMS kernel modules [ OK ]
Trying to register the VirtualBox kernel modules using DKMS[ OK ]
Starting VirtualBox kernel modules [ OK ]
如果出现以下错误, 是找不到内核对应的 kernel headers或内核版本不一致:
Stopping VirtualBox kernel modules [ OK ] Uninstalling old VirtualBox DKMS kernel modules [ OK ] Trying to register the VirtualBox kernel modules using DKMSError! echo Your kernel headers for kernel 3.18.7-200.fc21.x86_64 cannot be found at /lib/modules/3.18.7-200.fc21.x86_64/build or /lib/modules/3.18.7-200.fc21.x86_64/source. [FAILED] (Failed, trying without DKMS) Recompiling VirtualBox kernel modules [FAILED] (Look at /var/log/vbox-install.log to find out what went wrong)
查看内核版本:
[root@dev-zhanghua zhanghua]# uname -r
3.18.7-200.fc21.x86_64
查看已安装的内核版本:
[root@dev-zhanghua zhanghua]# rpm -qa|grep headers
kernel-headers-3.17.8-200.fc21.x86_64
glibc-headers-2.20-7.fc21.x86_64
发现版本不一致, 安装 kernel-headers-3.18.7-200.fc21.x86_64
yum install kernel-headers-3.18.7-200.fc21.x86_64
重启后二者版本一致：
[root@dev-zhanghua zhanghua]# uname -r 3.18.7-200.fc21.x86_64 [root@dev-zhanghua zhanghua]# rpm -qa|grep headers kernel-headers-3.18.7-200.fc21.x86_64 glibc-headers-2.20-7.fc21.x86_64
再次编译, 结果正常(编译VirtualBox 内核，如果失败,可能需要再次安装 dkms ):
[root@dev-zhanghua zhanghua]# /etc/init.d/vboxdrv setup Stopping VirtualBox kernel modules [ OK ] Uninstalling old VirtualBox DKMS kernel modules [ OK ] Trying to register the VirtualBox kernel modules using DKMS[ OK ] Starting VirtualBox kernel modules [ OK ]
