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
'/sbin/vboxconfig'
as root.
where: suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) - The support driver is not installed. On linux, open returned ENOENT.

不过/sbin/vboxconfig这个命令并没有
已经解决不了了，求大神帮个忙

重装virtualbox 再pacmac -Syu linux 重装内核就可以了

sudo modprobe vboxdrv

请问下archlinux的内核是怎么升级的，比如现在安装的archlinux是4.8.11的，怎么升级到4.8.15

这是正解;下面显示的是第一次输入：sudo /**in/vboxconfig之后显示的信息，然后安装
（apt-get install gcc make；
apt-get install linux-headers-3.16.0-4-amd64；
apt-get install linux-headers-amd64；）
这是终端显示的文件信息
root@debian:~# sudo /**in/vboxconfig
vboxdrv.sh: Stopping VirtualBox services.
vboxdrv.sh: Building VirtualBox kernel modules.
This system is not currently set up to build kernel modules (system extensions).
Running the following commands should set the system up correctly:
apt-get install gcc make
apt-get install linux-headers-3.16.0-4-amd64
(The last command may fail if your system is not fully updated.)
apt-get install linux-headers-amd64
vboxdrv.sh: failed: Look at /var/log/vbox-install.log to find out what went wrong.
This system is not currently set up to build kernel modules (system extensions).
Running the following commands should set the system up correctly:
apt-get install gcc make
apt-get install linux-headers-3.16.0-4-amd64

apt-get install linux-headers-amd64
There were problems setting up VirtualBox. To re-start the set-up process, run
/**in/vboxconfig
as root.
结束之后，再向终端输出：sudo /**in/vboxconfig
然后启动virtualbox就可以啦，当然一切还是靠运气
