解決Fedora安裝Virtualbox後無法運行:/etc/init.d/vboxdrv setup
在Fedora下安裝了Virtualbox，發現運行時出現以下問題：
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.
根據提示運行以root身份運行/etc/init.d/vboxdrv setup
結果提示：
Stopping VirtualBox kernel modules [確定]
Uninstalling old VirtualBox DKMS kernel modules [確定]
Trying to register the VirtualBox kernel modules using DKMSError! Bad return status for module build on kernel: 2.6.38.6-27.fc15.i686 (i686)
Consult /var/lib/dkms/vboxhost/4.0.8/build/make.log for more information.
[失敗]
(Failed, trying without DKMS)
Recompiling VirtualBox kernel modules [失敗]
(Look at /var/log/vbox-install.log to find out what went wrong)
解決方法：
1、可以先嘗試：
$su yum install -y kernel-headers kernel-devel dkms gcc
$su yum -y update
接著運行/etc/init.d/vboxdrv setup
如果執行此操作，仍然出現上述錯誤。可以參考第二步執行
2、先 安裝 PAE 包， $ yum install kernel-PAE-devel 。
完成後再執行 $ /etc/init.d/vboxdrv setup，則顯示：
Stopping VirtualBox kernel modules [確定]
Uninstalling old VirtualBox DKMS kernel modules [確定]
Trying to register the VirtualBox kernel modules using DKMS[確定]
Starting VirtualBox kernel modules [確定]
運行成功後，虛擬機可以運行成功！

用yum安裝的是開源的版本吧，直接從官網下載的包不會有這個問題
