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. Re-setup 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.
执行/etc/init.d/vboxdrv setup后，出现了以下的错误：
[root@localhost ~]# /etc/init.d/vboxdrv setup
Stopping VirtualBox kernel module [ OK ]
Recompiling VirtualBox kernel module [FAILED]
[root@localhost ~]# cat /var/log/vbox-install.log
重新编译Virtualbox驱动
[root@liukai ~]# /etc/init.d/vboxdrv setup
Stopping VirtualBox kernel module [确定]
Recompiling VirtualBox kernel module [确定]
Starting VirtualBox kernel module [确定]
就可以了。
产生原因可能是ubuntu升级所造成的！
