Open Stack

Hi Tyler,

You might try verifying that the instance properly received its IP address. You can try using ‘nova console-log <id>’ to view the console log of the instance. Look for the cloud-init info. Also, take a look at the syslog of the network node to see if the DHCP request made it and was acknowledged. If it looks like it got its IP, try hitting the instance from within the DHCP or router namespace to see if you can hit the fixed IP from something in the same network before trying to hit the floating IP. You may also want to run some packet captures on the respective qbr bridge and physical interfaces while doing these tests to see if/where traffic is getting dropped.
