vbox kernel modules should be signed for OL7

[dbv]

For OL7 running on a server with Secure Boot installation of VirtualBox will fail:

fslin1:/root # yum install VirtualBox-5.1 ... Running transaction

Installing : VirtualBox-5.1-5.1.30_118389_el7-1.x86_64 1/1

Creating group 'vboxusers'. VM users must be member of that group!

vboxdrv.sh: failed: modprobe vboxdrv failed. Please use 'dmesg' to find out why.

There were problems setting up VirtualBox. To re-start the set-up process, run

/sbin/vboxconfig

as root.

Verifying : VirtualBox-5.1-5.1.30_118389_el7-1.x86_64 1/1

Installed:

VirtualBox-5.1.x86_64 0:5.1.30_118389_el7-1

Complete''

The reason for failure is the absence of module signature:

fslin1:/root # modprobe vboxdrv modprobe: ERROR: could not insert 'vboxdrv': Required key not available

And the module is not signed:

fslin1:/root # cd /lib/modules/uname -r/misc fslin1:/lib/modules/4.1.12-94.3.9.el7uek.x86_64/misc # ls vboxdrv.ko vboxnetadp.ko vboxnetflt.ko vboxpci.ko fslin1:/lib/modules/4.1.12-94.3.9.el7uek.x86_64/misc # modinfo vboxdrv.ko filename: /lib/modules/4.1.12-94.3.9.el7uek.x86_64/misc/vboxdrv.ko version: 5.1.30 r118389 (0x002a0000) license: GPL description: Oracle VM VirtualBox Support Driver author: Oracle Corporation srcversion: 8FBD7594E804ED618ED1A07 depends: vermagic: 4.1.12-94.3.9.el7uek.x86_64 SMP mod_unload modversions parm: force_async_tsc:force the asynchronous TSC mode (int)

There is no 'signer', 'sig_key' & 'sig_hashalgo' in the above. Would you be able to sign VBox modules accordingly?
