where can I find the VB Kernel Driver for kernel 3.12.7-300.fc20.x86_64? Yum upgraded my kernel, but cannot find the newest virtualbox kernel drivers, so virtualbox fails during start up of a virtual machine. I use the virtualbox repository on Fedora 20.

Edit: Output from

rpm -qa kernel\* ; uname -r

Thanks :)

Do you have dkms installed? If not do so by sudo yum install dkms. After that run sudo /etc/init.d/vboxdrv setup.

DKMS automatically builds module when a new kernel is installed. Everything should be fine after that. You are using repo, correct?

I installed dkms and it worked again like a charm. Thanks to all!

Hi, if you use VirtualBox from rpmfusion, sometimes we got a little delay on updates , you could enable repo rpmfusion-free-updates-testing

yum --enablerepo=rpmfusion-free-updates-testing update

Also you should have kmod-VirtualBox installed (metapackage which tracks in VirtualBox kernel module for newest kernel) , which just let you install kernel when kmod is available .

yum install kmod-VirtualBox

I don't know about VB drivers but I do know that you need kernel-devel equal to the running kernel. Since your kernel was just updated perhaps kernel-devel needs to be installed? Post

rpm -qa kernel\* ; uname -r

@Glenn: I've updated my question with the output

Can you run /etc/init.d/vboxdrv setup? It may not be available since you're using the Fedora version of VirtualBox. If there is a kernel update everything needs to be rebuilt. With the VirtualBox rpm from Oracle you never need to deal with this if you install akmod-VirtualBox.

Looks to me like you haven't rebooted to the newest kernel. You need to do that.

FWIW, if you use the upstream rpm (not the one from rpmfusion repos) you don't need akmod-VirtualBox, the upstream rpm uses DKMS to build the kernel module(s) for the currently running kernel; when a new kernel is installed the module is rebuilt for it automatically IIUC.
