Hi Adam, James, Thanks for the quick response.
The upstream change is here: http://openvswitch.org/cgi- bin/gitweb.cgi?p=openvswitch;a=commit;h=11f84dce005dd14a374ab2ef5f8c25bcf8285a36 In our testing, VMs frequently send out IPv6 neighbor discovery packets (the v6 equivalent of ARP) during boot. When the OVS Quantum plugin is running in tunnel mode (new default), this causes OVS to crash and wipe all flow state from its configuration. I can put you in touch with the the appropriate OVS developer if you like, as we both work at Nicira. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1021530 Title: update to include stable fixes for OVS 1.4 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openvswitch/+bug/1021530/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
