今天突然ubuntu下的virtual box出问题了

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/rcvboxdrv 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.

where: suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) - The support driver is not installed. On linux, open returned ENOENT.

解决办法：ubuntu 16.04

sudo apt-get upgrade

sudo apt-get update

sudo apt-get install dkms  

sudo apt-get install linux-headers-`uname -r` build-essential  

sudo ./sbin/vboxdrv setup
