Instances Not Getting DHCP Lease
I realize this is a common question, and I've looked through many of the answers from previous posts, but I'm afraid I'm new enough to OpenStack that I wasn't able to make sense of many of the replies and was unable to solve my problem after searching.
I have a multi-node deployment with one controller/network node and two compute nodes. When I create a cirros image on the Compute node, I see in the Horizon interface that a DHCP address is assigned, but when I run ifconfig
in the VNC console on the Horizon dashboard, I see the instance has no IP address.
I ran tcpdump -n -i eth3
on both the controller node and the compute node. What I am seeing is that the compute node gets a DHCP request and sends a reply. However, the compute node shows me only the request and not the reply.
Can anyone suggest possible fixes? As I said, I'm pretty new to OpenStack. I'm sure that I haven't provided all of the information needed to solve this problem; if someone could tell me what further information would be useful (and how to generate a report with that information), I'll be happy to update my question with that information.
Thanks!
