Thanks for reporting this bug and the detailed reproduction instructions. I would mark it high, but since you offer a workaround I'll mark it medium instead.
What does your /etc/modprobe.d/bonding show? I've not used this combination myself, but from those who have, a few things do appear fragile, namely: 1. if you are using 802.3ad, you need trunking enabled on the physical switch 2. some people find that turning stp on helps (http://www.linuxquestions.org/questions/linux- networking-3/bridging-a-bond-802-3ad-only-works-when-stp-is- enabled-741640/) But I'm actually wondering whether this patch: http://permalink.gmane.org/gmane.linux.network/159403 may be needed. If so, then even the natty kernel does not yet have that fix. I am marking this as affecting the kernel, since I believe that is where the bug lies. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
