[Rdo-list] Compute nodes instances aren't obtaining DHCP addresses

[St. George, Allan L.]

We currently have a multi-compute node stack (controller, network, block storage & 3 compute nodes.)

Upon spawning an instance, it resizes to match the flavor, then it attempts to obtain an ip address for eth0 prior to cloud-init.  The process failes.

The network node (rdo3) /var/log/nova/scheduler.log is reporting...
