I've now updated to Saucy and I still have the same problem on multiple machines with openswitch.
I have a KVM test machine that has a ubuntu VM running on it plugged into a vswitch that is in turn plugged in via the quad port bond you can see here. Iron is the KVM host, the host shows no mDNS activity, I can't get .local resolution in or out and if I use avahi-browse -a I can't see anything at all on the network. The same network but on a VM inside Iron running via openvswitch and it works fine as can be seen at the end. root@iron:~# uname -a Linux iron 3.11.0-13-generic #20-Ubuntu SMP Wed Oct 23 07:38:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux root@iron:~# dpkg-query -W openvswitch-switch openvswitch-switch 1.10.2-0ubuntu2 root@iron:~# ovs-vsctl show cd554298-25b0-4b64-a472-78f130d011c2 Bridge embedded Port "bond0" Interface "em0" Interface "em1" Port "mgmt0" Interface "mgmt0" type: internal Port embedded Interface embedded type: internal Bridge internal Port "internal0" Interface "internal0" type: internal Port internal Interface internal type: internal Port "vnet4" Interface "vnet4" Bridge quadport Port "vnet2" Interface "vnet2" Port "bond1" Interface "qp1" Interface "qp3" Interface "qp0" Interface "qp2" Port "quadport0" Interface "quadport0" type: internal Port quadport Interface quadport type: internal Port "vnet1" Interface "vnet1" Port "vnet0" Interface "vnet0" Port "vnet3" Interface "vnet3" ovs_version: "1.10.2" tim@ubuntu:~$ uname -a Linux ubuntu 3.11.0-12-generic #19-Ubuntu SMP Wed Oct 9 16:20:46 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux tim@ubuntu:~$ avahi-browse -a + eth0 IPv6 iconnect [70:1a:04:50:b6:d0] Workstation local + eth0 IPv6 backups-gmail [52:54:00:41:37:4b] Workstation local + eth0 IPv6 ubuntu [52:54:00:ab:e6:e5] Workstation local + eth0 IPv4 iconnect [70:1a:04:50:b6:d0] Workstation local + eth0 IPv4 backups-gmail [52:54:00:41:37:4b] Workstation local + eth0 IPv4 ubuntu [52:54:00:ab:e6:e5] Workstation local -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openvswitch in Ubuntu. https://bugs.launchpad.net/bugs/1223730 Title: mDNS failure with openvswitch 1.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openvswitch/+bug/1223730/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
