I read the mail and did a first round of test before I could check the setting of the switch. Here are the transcript of the test with balance-rr.

Now that I have full access to our switch, I will do more tests tomorrow. As far as I know, the switch is doing automatic trunking so the switch should not be an issue. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/785668 Title: bonding inside a bridge does not update ARP correctly when bridged net accessed from within a VM -- 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
