I’m running into an issue with libvirt-lxc networking. I have an init
program that configures the eth0 interface with an IP and gateway when the container
starts. I noticed that programs running in the container encountered “no route to host”
errors and looked into it further. What I found is that ARP packets are not making it onto
the gateway during the first few seconds of the container’s life.
I found the issue: STP was enabled on the virbr0 which spends 2s in each of the Listening
and Learning states by default before enabling the interface.
A simple `brctl stp virbr0 off` solves this issue.
