Bug Description

Up-to-date quantal install:

FATAL: Module openvswitch_mod not found.
 * Inserting openvswitch module
Module has probably not been built for this kernel.
For instructions, read
/usr/share/doc/openvswitch-datapath-source/README.Debian
FATAL: Module openvswitch_mod not found.
 * Inserting openvswitch module

I think its still using old naming for the module.

Any advice from upstream on how to deal with this? When will a version of openvswitch be released which directly supports the 3.5 kernel module naming? or we could carry a patch in Ubuntu in the interim if that works OK.

Help appreciated.

I'll try a cherry pick of this commit.

---------------
openvswitch (1.4.2+git20120612-2ubuntu1) quantal; urgency=low

  * Fix openvswitch-switch startup with 3.5 kernel module name, allowing
    use of openvswitch without openvswitch-datapath-dkms (LP: #1021078):
    - d/patches/kernel_3.5_support.patch: Cherry picked patch from upstream
      VCS to align module naming with openvswitch module in 3.5 kernel.
