virtual box in fedora is still on 5.0.16. (i just did a dnf update to check if it would change but keeps saying 5.0.16)
@mumbler Why you want to play with Virtualbox? Fedora has perfect alternatives with the virt-manager (needs to be installed separately since Fedora uses by default Gnome-boxes but this is a similar tool without configuration possibilities). that handles KVM/Qemu (this is also installed by default in Fedora). Else i would suggest using dnf install virtualbox or better play with docker thatch the latest fashion in virtualization.
RE: The Cable, I have a *.vmdk built in VB that I use and I don't want to change. As of now, if I have to run a script to access USB devices that's acceptable.
Eden - I have no idea what vboxs or fedoras means. If you are asking what repository I'm using, it's rpmfusion, which works great. I don't consider the "problem" to be with VirtualBox or even Fedora, it's the security policy of SELinux. And I don't consider it a "problem" it's just the way security works. However, finding out what was going on was a real pain in the neck.
