Problema do kernel ao instalar o VirtualBox

Question

No meu Fedora 24, depois de instalar e executar o VirtualBox (do repositório VB) com este comando:

# dnf install VirtualBox-5.1-5.1.4_110228_fedora24-1.x86_64
$ virtualbox

Uma janela pop-up mostra-me um Kernel driver not installed (rc=-1908) , o que é bastante clássico de acordo com uma pesquisa no google. Este mesmo erro sugere a execução de /sbin/vboxconfig :

    vboxdrv.sh: Building VirtualBox kernel modules.
This system is not currently set up to build kernel modules (system extensions).
Running the following commands should set the system up correctly:

  yum install kernel-core-devel-4.5.5-300.fc24.x86_64
(The last command may fail if your system is not fully updated.)
  yum install kernel-core-devel
vboxdrv.sh: failed: Look at /var/log/vbox-install.log to find out what went wrong.
This system is not currently set up to build kernel modules (system extensions).
Running the following commands should set the system up correctly:

  yum install kernel-core-devel-4.5.5-300.fc24.x86_64
(The last command may fail if your system is not fully updated.)
  yum install kernel-core-devel

There were problems setting up VirtualBox.  To re-start the set-up process, run
  /sbin/vboxconfig
as root.

Eu notei que

# rpm -qa kernel |sort -V |tail -n 1
kernel-4.6.6-300.fc24.x86_64
# uname -r
4.5.5-300.fc24.x86_64

Então eu acho que pode vir disso, mas eu não sei como resolver essa diferença nas versões do kernel.

Eu tentei, como o comando /sbin/rcvboxdrv setup sugere:

vboxdrv.sh: Building VirtualBox kernel modules.
This system is not currently set up to build kernel modules (system extensions).
Running the following commands should set the system up correctly:

  yum install kernel-core-devel-4.5.5-300.fc24.x86_64
(The last command may fail if your system is not fully updated.)
  yum install kernel-core-devel
vboxdrv.sh: failed: Look at /var/log/vbox-install.log to find out what went wrong.

Eu tentei instalar, nada mudou.

Outra coisa, tenho uma pasta /usr/src/vboxhost-5.1.4/ , mas:

# dkms install vboxhost/5.1.14
Error! Could not find module source directory.
Directory: /usr/src/vboxhost-5.1.14 does not exist.

PS: você pode perguntar que /var/log/vbox-install.log ("Arrêt" significa parar):
