Issue DM-5926: networking in strange state for newly created instances
When starting a new instance, occasionally something strange seems to happen with the network setup. The instance will come up but is inaccessible (icmp, ssh). When this happens, the console log shows that a DHCP address was obtained and cloud-init injected ssh-keys, so it isn't a total network setup failure. I have seen this happen a few times in the last couple of weeks but I can't reliably reproduce it. I'm wondering if neutron is logging anything interesting when this happens. This failure mode happened again a few minutes ago with 7adffa82-7221-454c-acfe-5f21cdd34ea8. Which I killed and recreated as instance b6f64981-099b-46e5-a27e-e3694372f447 with the same private IP address. The new instance is accessible as expected.
