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 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-$(uname -r) akmod-VirtualBox # User is advised to run this after upgrades /sbin/modprobe -r -b vboxnetflt &>/dev/null ||: /sbin/modprobe -r -b vboxnetadp &>/dev/null ||: /sbin/modprobe -r -b vboxdrv &>/dev/null ||: akmods systemctl restart systemd-modules-load dmesg | grep -i vbox
Fedora as a Virtual Machine
Install VirtualBox-guest. VirtualBox-guest replaces !VBoxGuestAdditions for Fedora itself, VirtualBox-guest is just to install in a vm guest system, You can't install VirtualBox-guest in a host system. Therefore VirtualBox-guest conflicts with VirtualBox by design.
RPMFusion doesn't provide VBoxGuestAdditions for others OS , you have to download it , you have a button for that in VirtualBox, vm manager menu.
dnf install VirtualBox-guest kernel-devel-$(uname -r) akmods systemctl restart systemd-modules-load systemctl restart vboxservice dmesg
In the last lines should see soemthing like :
