Hello

I had the exactly same problem were the network stoped working after a
reboot in the network node.
The easy solution I could found was to delete all the networks and VMs and
create them again.
Everything is working fine since that, but I didn't reboot the node again
to test it.

Aaron, can you give an explanation of what the problem is, or point to your
patch? Thank you.

Regards
