Thanks a lot!

Before adding anything to our FAQ we would like to understand what went wrong with your installation. And DKMS is already mentioned in the documentation. I assume you installed the Jaunty package from our website. The question is why the module was apparently not properly installed during the first time you installed VirtualBox.

[Dmitry]

All I can say, - no error messages went on first installation and there can be a better way to inform user about same error (kernel modules not loaded). I spent much time to find way out.

In any case, thanks a lot, great product.

#service vboxdrv setup This helped me. Kernel modules was removed, rebuilded and reloaded.

I have just upgraded Ubuntu netbook remix 9.10 to 10.4 (and VirtualBox OSE seemed to be updated to the last 3.1.6). After that my VMs didn't run. And the host-only interface (vboxnet0) disappeared and failed to be created with the error: "Failed to execute 'VBoxNetAdpCtl add' (exit status: 768)".

The only worked out solution I found at ​http://fedoraforum.org/forum/showthread.php?p=1332225: After this command VB started with the host interface appeared.

sudo insmod /lib/modules/2.6.31-21-generic/updates/dkms/vboxnetadp.ko

Same problem after upgrade of Kubuntu 9.10 to 10.4. Using VirtualBox DEBs from ​http://download.virtualbox.org/virtualbox/debian and have 3.1.6 r 59338 installed.

vboxnetflt and vboxnetadp modules did not load because of missing symbols, similar to bug #5817

The following command solved the problem:

sudo /etc/init.d/vboxdrv setup

I had no idea that DKMS compilation failed during O/S upgrade and only found out after searching online for the error message issued at VM startup failure: "Failed to execute 'VBoxNetAdpCtl add' (exit status: 768)". The information in this bug helped in finally tracking down the problem in vboxnetadp.

I agree with skyman that it would be helpful if error messages about e.g. missing host-only networks would contain a hint that this might be due to a missing vboxnetadp module in the running kernel. Even better would be if VirtualBox could detect presence of the required kernel modules at startup and issue warnings if not found.

[Martin Kalén]

For the record, this now seems to happen after every kernel upgrade. Just got Linux 2.6.32-22-generic kernel through Ubuntu 10.04 LTS upgrades and DKMS seems to have failed to compile the VirtualBox modules again (except for vboxdrv which works out of the box).

Again, this command fixes the problem with vboxnetadp:

sudo /etc/init.d/vboxdrv setup

Is there any chance of getting a VirtualBox package for lucid (Ubuntu 10.04 LTS) where the correct DKMS compile order is ensured?

[Frank Mehnert]

Tell me how one can ensure the correct DKMS order and we will fix it.

[Martin Kalén]

I have initiated contact with the Debian DKMS maintainers and will try to get some help from there. I still suggest you add some info about "possible missing vboxnetadp kernel module" in the errors mentioned in this bug.

Regarding the underlying DKMS problem, I will add furher info (if I get some response from the DKMS team) in bug #5817, since 5817 better describes what goes wrong. This bug is a consequence/symptom of 5817.

Replying to nikbox:

I have just upgraded Ubuntu netbook remix 9.10 to 10.4 (and VirtualBox OSE seemed to be updated to the last 3.1.6). After that my VMs didn't run. And the host-only interface (vboxnet0) disappeared and failed to be created with the error: "Failed to execute 'VBoxNetAdpCtl add' (exit status: 768)".

I've totally fixed it by removing every VirtualBox related package, cleaning 'tails' with 'Janitor' and installing VB again.

[Frank Mehnert]

This is actually a duplicate of #5817 and should be finally fixed in the upcoming 3.2.10 release.
