vm will not launch if network is set to bridge

[Jorge Rama]

I have a virtual machine in Virtualbox with a network adapter in bridge mode and it will not start since updating to Ubuntu 13.10 showing the following error:

Failed to open/create the internal network 'HostInterfaceNetworking-eth0' (you might need to modprobe vboxnetflt to make it accessible) (VERR_INTNET_FLT_IF_NOT_FOUND).
Failed to attach the network LUN (VERR_INTNET_FLT_IF_NOT_FOUND).

The error tells me to run modprobe vboxnetflt in terminal but the error persists even after running the command.

Status changed to 'Confirmed' because the bug affects multiple users.

Dito - same here. Newest VirtualBox, Ubuntu 13.10 x64, bridged guest.

As a test I tried installing the deb file available at the virtualbox website: http://download.virtualbox.org/virtualbox/4.2.18/virtualbox-4.2_4.2.18-88780~Ubuntu~raring_amd64.deb

I managed to install it without issue at confirmed that my vm will run correctly.

@jorgehsrama: Not sure about the bug reporter, but I'm experiencing this when using the latest VirtualBox from the standard Ubuntu repositories. I didn't try the upstream packages, but that might explain why it does work for you and not for me?

[Jorge Rama (jorgehsrama)]

@marten-de-vries I am the bug reporter, but I tried using the version available on the virtualbox website and it works properly.

[Marten de Vries (marten-de-vries)]

@jorgehsrama: Ah, forgot checking that, sorry. Then we're saying the same. :)

I also suffer from this. I can confirm that it does not work in brdged mode. Further-more I can add that the problem is also present when having a network adapter set to "Host-only adapter"

I can use the latest virtualbox by running a 3.10 kernel. AFAIK, this is a problem in the 3.11 series (check the upstream bug reports)

[Eric B (ebischoff)]

Still no joy in this morning's 3.11.0-8 kernel (saucy) with stock virtualbox 4.2.16.

[shankao (shankao)]

Note that the virtualbox package needs to be upgraded to upstream version 4.2.18, or the specific patch applied to Ubuntu's package.
AFAIK, that's in debian and, in order to solve this problem, it needs to be synchronized from them into ubuntu.

Sync request for package in debian to fix this bug 1228569.

[Felix Geyer (debfx)]

Fixed with virtualbox 4.2.16-dfsg-3

[Eric B (ebischoff)]

Confirmed, fixed in today's virtualbox packages. Thank you!
