Kernel panic on host OpenSUSE when VM is using bond interface

[cduchenoy]

I have a host running OpenSUSE 11.3 with severals guests running Linux VMs. This server uses 2 lan interfaces (1 Gb/s and 100 mB/s) configured as a bond0 active-passive interface. No problem whith all versions on virtualbox since 3.0, but kernel panic occured with version 4.0.0. I create an other server with minimal configuration and 1 interface bond0 with only 1 lan interface : same problem ! So I backgrade version with 3.4 and it works well again...

I believe you have the same problem as described in #7879. Please apply the attached patch in the directory where you have installed VirtualBox with

sudo patch -p0 -i <path-to-qdisc_noqueue.patch>

then rebuild the modules with

sudo /etc/init.d/vboxdrv setup

Replying to aleksey:

Thank you. It's perfect. After applying the patch, I can now use the bond interface.
