About this Howto
The goal is have a place with all information that is FAQ.
Since F22+ we don't have pre-built kmods we need use akmods.
dnf install VirtualBox kernel-devel-$(uname -r) akmod-VirtualBox akmods systemctl restart systemd-modules-load.service dmesg | grep -i vbox

First time installation
The installation of VirtualBox-server package, will created the "vboxusers" group.
For each user that you want run VirtualBox, please do as root:
usermod -a -G vboxusers username ( usermod -a -G vboxusers sergiomb )
or use the GUI Users and Groups tool.
Sign kernel modules to work with secure boot
To sign kernel modules to make work with secure boot, this 2 posts are a good reference, I haven't test my self:
or google for "virtualbox fedora secure boot" ,
1- If you don't need usb or just for testing , go to setting usb and disable usb , for that you have to have vm machine off .
2 - With firefox download Oracle_VM_VirtualBox_Extension_Pack-5.1.30.vbox-extpack for example click here : http://download.virtualbox.org/virtualbox/5.0.14/Oracle_VM_VirtualBox_Extension_Pack-5.0.14.vbox-extpack firefox should ask if you want install with vbox something , say yes
3 - After try file -> check for updates , also should install the correct extpackage
if this doesn't do nothing because you install a superior version
rm -rf /usr/lib64/virtualbox/ExtensionPacks/Oracle_VM_VirtualBox_Extension_Pack as root , and repeat items 2 and 3
anyway , you should use file -> check for updates to update extension pack
Upgrade VirtualBox version without reboot
On upgrade VirtualBox for a new release, we need remove kernel modules loaded and load new ones (for the new release).
dnf update VirtualBox kernel-devel-$(uname -r) akmod-VirtualBox akmods-shutdown # User is advised to run this after upgrades /sbin/modprobe -r -b vboxnetflt /sbin/modprobe -r -b vboxnetadp /sbin/modprobe -r -b vboxdrv /sbin/modprobe -r -b vboxpci /sbin/modprobe -r -b vboxdrv systemctl restart systemd-modules-load dmesg | grep -i vbox
if you run an upgrade version don't forget update also VirtualBox_Extension_Pack (if you have it installed) http://rpmfusion.org/Howto/VirtualBox#Install_VirtualBox_Extension_Pack
Fedora as a Virtual Machine and VBoxGuestAdditions
If you want run Fedora in a vm, you may/should install VirtualBox-guest-additions.
VirtualBox-guest-additions replaces VBoxGuestAdditions for Fedora, VirtualBox-guest-additions is just to install in a vm (guest system), You can't install VirtualBox-guest-additions in a host system. Therefore VirtualBox-guest-additions conflicts with VirtualBox by design.
RPMFusion doesn't provide VBoxGuestAdditions for others OS , you have to download it , you have a button for that in VirtualBox, vm manager menu.
dnf install VirtualBox-guest-additions kernel-devel-$(uname -r) akmods systemctl restart systemd-modules-load systemctl restart vboxservice dmesg
In the last lines should see something like :

I had install kernel-debug-devel but I need kernel-devel
When we install only VirtualBox dnf install VirtualBox it require one kmod so it pulls akmod-VirtualBox (we, at this moment, don't have binary kmods) and also may pulls in kernel-debug-devel instead of kernel-devel (of the running kernel) . We need the kernel-devel of kernel that is running on the system but we can't workaround this problem. So we need make sure that install proper kernel-devel (usually the kernel-devel).
dnf install kernel-devel-$(uname -r) dnf remove kernel-debug-devel
VirtualBox kernel modules fail to load with systemd-modules-load.service
Unfortunately SELinux prevents to load vbox modules , so we need disable selinux.
Selinux and VirtualBox
ATM, we don't support running VirtualBox with selinux enabled, solution is disable selinux.
