Hi Dan,
some info about my network setup:
- My bond is used only for VM networking. ovirtmgmt has a dedicated
ethernet card.
- I haven't set any ethtool opts.
- Nics on bond specs:

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*?
