I have not been able to reproduce the problem except between containers 
running on different hosts. Behavior is the same for lxc and libvirt-lxc.

I did try this, using 54:C0:xx:xx:xx:xx for my mac addresses. It did not 
help.

I tried stp on and off, as well as setting a delay to 0 and sleep to 1. 
No luck.

If I pre-populate everyone's arp tables, this solves the problem, but 
that's not a practical solution.
