Thanks for the kind advice. Tried this:
/usr/local/src/openvswitch-2.3.2# ./configure --prefix=/usr --localstatedir=/var --with-linux=/lib/modules/`uname -r`/build And got this: configure: error: Linux kernel in /lib/modules/3.16.0-4-amd64/build is version 3.16.7, but version newer than 3.14.x is not supported (please refer to the FAQ for advice) How do I compile and install the kernel modules?

All of this seems pretty normal looking. Here's another thing to try if you can: I think that you are probably running the kernel module that is part of the upstream kernel in Debian. Since this problem appears to be isolated to Debian, maybe somehow there is an issue in the version of the OVS kernel module that they picked up. Can you try compiling and installing the module that is packaged with OVS 2.3? I guess either than will fix the issue (as it has been out a while and nobody has reported a problem) or the issue is somewhere else in the stack and it will continue even if you swap out OVS for the Linux bridge. _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
