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.
May you dump the arp traffic (maybe together with icmp) on the host? I'm
interested in what happens in/around moment the gateway is pinged!
On the bridge, did you set forward delay to 0, a low hello intervall (e.g. 1s)
and turn on STP?
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.
