我从12.10升级到14.04之后出现一些问题，是在不知道该怎么解决了！

目前是APACHE 无论我怎么设置好像都没有什么用，老是显示:
Forbidden

You don't have permission to access / on this server.
Apache/2.4.7 (Ubuntu) Server at localhost Port 80

虚拟机也出现问题，不能打开原来的虚拟程序。

报如下错误：

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. 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.

还有就是 有线网卡老是不能自己连接，总要手动通过命令来启动。不知道为什么

有知道的兄弟能给支个招吧！
