app-emulation/virtualbox-modules-4.2.4 fail to load on 3.7 kernel with
gucky linux # modprobe vboxdrv
FATAL: Error inserting vboxdrv (/lib/modules/3.7.0-gentoo/misc/vboxdrv.ko): Required key not available
this happens with other ebuilds which create kernel modules as well (see Bug 426406)
sorry, I meant bug 447352
This is something I won't be able to test in the near future. Unless someone else is coming up with a sane solution it will take a while until I can take care of this bug.
This is my workaround solution:
for x in /lib/modules/`uname -r`/misc/vbox*.ko; do sudo perl /usr/src/linux/scripts/sign-file /usr/src/linux/signing_key.priv /usr/src/linux/signing_key.x509 $x; done
I don't think there is any reason for a virtualbox-specific bug to remain open here, this issue affects all packages providing external modules and will (hopefully) be fixed at the linux-mod.eclass level.
