在 Fedora 下安装了 Virtualbox，发现运行时出现以下问题：
Kernel driver not installed (rc=-1908)
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. Users of Ubuntu, Fedora or Mandriva should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary.
然后以 root 身份运行/etc/init.d/vboxdrv setup 结果提示：
Stopping VirtualBox kernel modules [确定] Uninstalling old VirtualBox DKMS kernel modules [确定] Trying to register the VirtualBox kernel modules using DKMSError! Bad return status for module build on kernel: 3.2.3-2.fc16.i686 (i686) Consult /var/lib/dkms/vboxhost/4.0.8/build/make.log for more information.[失败] (Failed, trying without DKMS) Recompiling VirtualBox kernel modules [失败] (Look at /var/log/vbox-install.log to find out what went wrong)
解决方法： 先尝试：
1 | sudo yum install -y kernel-headers kernel-devel dkms gcc |
如果执行此操作，仍然出现上述错误。可以参考下面 安装 PAE 包， sudo yum install kernel-PAE-devel 。 完成后再执行 sudo/etc/init.d/vboxdrv setup
