So my virtualbox windows wouldn’t start after installing Ubuntu 15.10 and ask me to perform the vboxdrv setup after every reboot. The reason is that vboxdrv not starting on boot, with Ubuntu 15.10. This did the trick for me:
To quickly find content that references a specific content id within CoreMedia7 check the CM command line tools. You’ll find a query command which allows you to execute content queries from the command line.
So a neighbor of mine came up to me with a VTech KidiGo. It’s a kids audiobook, mp3 and video player. And it’s a horrible one at that. You either have the choice to buy audio files and videos from VTech, or you’ll have to put up with a video player that only accepts a strange format.
So this neighbor came up to me wanting to put videos on this thing and of course nothing really worked. Everything I tried failed on the KidiGo with “Invalid Format”. Finally I tried to transcode the video with ffmpeg and what worked was the following:
I recently upgraded my Fedora 20 with the latest kernel and came across an issue when I wanted to boot my Windows VM. VirtualBox told me to setup vboxdrv again, which refused to work, stopping the the error message:
DKMS: add completed. Failed to install using DKMS, attempting to install without Makefile:183: * Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR=<directory> and run Make again. Stop.</directory>
The only thing that helped was to remove VirtualBox altogether.
yum remove VirtualBox-4.3
And then reinstall it from rpmfusion with the kmod meta-package which install VirtualBox alongside the correct kernel sources.
yum install VirtualBox kmod-VirtualBox
After installing the VirtualBox extensions I was able to bring my Windows VM back up.
