Netfilter modules don't work on Kernel 3.11-rc1+ => Fixed in SVN

[Mal_Haak]

When running on Kernel 3.11-rc1 and above the kernel modules build without error and load without error. However when attempting to use them, the VM's cannot start. Also Host-only networks disappear at random and sometimes cannot be created.

/etc/init.d/vboxdrv setup output:

It also behaves the same way for other netfilter based interface options (like bridge)

Reproducible here. ATM I think this could be a regression in the Linux kernel.

Actually the kernel interface changed slightly (void pointers are evil). Fixed in r47484. This fix will be part of the next maintenance release.

Fixed in VBox 4.2.18.
