Hello
With the last system update I have seem a message in system start up about
a error loading kernel modules, after that VirtualBox do not start because
the apropiate module can not been loaded.
https://bugzilla.redhat.com/show_bug.cgi?id=1426836
There is another report about VirtualBox not running:
https://bugzilla.redhat.com/show_bug.cgi?id=1427525
I do not like VirtualBox but I need it because I am working with a web app
than only provides a .ova file to work locally and looks like I am not the
only one that can not start VirtualBox after updating Fedora 25, trying old
kernels do not work for me :(
Regards
