I guess that code cannot compile under kernel 3.13, as they removed numa_next_reset and some other NUMA functions.
I think I found the offending commit here: http://git.kernel.org/cgit/linux/kernel/git/tip/tip.git/commit/?id=930aa174fcc8b0efaad102fd80f677b92f35eaa2 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1254803 Title: virtualbox-guest-dkms 4.2.16-dfsg-3: virtualbox-guest kernel module failed to build [error: ‘struct mm_struct’ has no member named ‘numa_next_reset’] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1254803/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
