VirtualBox Kernel Module no longer builds under -current kernel update of 17-Nov-2017


I just updated my kernel today but now the VirtualBox kernel module no longer builds. This affects 5.1.30 and 5.2.0 (at least).

The last messages in the log file are here:

Code:

Any idea what is happening?

You can give the development snapshots for 5.2.1 a try. I could get it to build on my 14.2 system with the 4.14 kernel.

Thanks. I tried that and it compiled but there was an error on load. Here are the dmesg lines

Code:

you can also consider downgrading your kernel to a version supported by virtualbox.

I can confirm problems with 5.2.0, but I was able to compile against 4.14/-current when I downgraded both virtualbox and addons to 5.1.30

On my installation, 5.1.30 did not compile. I got the same error as with 5.2.0.

AFAIK, vboxpci is not required for VirtualBox to work. It seems to work on my computer with the same error. It might just prevent passthrough (if that's what it's used for).

I haven't compiled VB in Current, but today I successfully installed the 5.1.30 GA in Current after updating to the 4.14 kernel.

The version on www.virtualbox.org/wiki/Testbuilds is now VirtualBox 5.1.31 and that compiled fine on current with kernel 4.14.0 (incl guest additions and extension pack)

I get the same error in dmesg from vboxpci.

To the other poster, who said it would run without, in my case, my Win7 virtual machine will not start.

Correction. When I installed the 5.1.31 guest extensions the virtual machine started. This may mean the 5.2.1 version would have worked if I had done that (though I though I had).

Bottom line -- up and running.

Thanks for all the advice.

Wow! willysr, that was quick.

I look forward to trying it when I get a chance.

Ok, I checked dmesg and also had the vboxpci symbol not found error:
Code:
bash-4.4$ dmesg | grep vboxpci
[   29.387902] vboxpci: Unknown symbol vfs_write (err 0)
bash-4.4$ sudo dmesg | grep vbox

[   29.387902] vboxpci: Unknown symbol vfs_write (err 0)
Then only applied this part of Willy's patch changing vfs_write (the changes for /vboxnetflt/linux/VBoxNetFlt-linux.c did not need to be made for 5.1.31)
