The brcompat module does work in raring; however you need to make sure that
1) you are using the dkms version of the openvswitch module, not the stock kernel one You can do this by stopping the openvswitch-* daemons, unloading the openvswitch module and then reloading it to pickup the dkms version sudo service openvswitch-switch stop sudo rmmod openvswitch sudo modprobe openvswitch Always make sure that you install the DKMS package prior to installing openvswitch-switch itself other wise you may hit this issue. 2) make sure that you don't already have the bridge module loaded sudo rmmod bridge After ensuring 1 & 2 are OK then you should be able to load the brcompat module. BUT - please note this module is deprecated upstream and will disappear - so try to move to using openvswitch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1094830 Title: brcompat failed to be loaded To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openvswitch/+bug/1094830/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
