I know, from reading the release notes of 7.2, that there were some changes to the bonding bits in the kernel so i'm guessing maybe some defaults have changed. I'll keep digging and post back as soon as i have something. Jon On 29/12/15 19:55, Stefano Danzi wrote:

Hi Jon and Stefano, We've been testing bond mode 4 with (an earlier) kernel-3.10.0-327.el7.x86_64 and experienced no such behaviour. However, to better identify the suspected kernel bug, could you provide more information regarding your network connectivity? What is the make of your NICs? Which driver do you use? Do you set special ethtool opts (LRO with bridge was broken in 7.2.0 kernel if I am not mistaken)? You have the ovirtmgmt bridge on top of your bond, right? Can you share your ifcfg*?

I made some tests using kernel 3.10.0-327.4.4.el7.x86_64. I did a TCP dump on virtual interface "DMZ" (VLAN X on bond0). When I have two netwok cables connected I can se ARP requests but not ARP replyes. When I detach one network cable I can see ARP requests and ARP replyes (and networking on VM works). Maybe the problem isn't in bonding config but in qemu/kvm/vhost_net....
