I'm stumped. I am trying to add a new off-site zone, which I've already done 3 times from the same management server. This fourth system is thwarting my efforts. It should be a clone of the process I used on the last two. The only delta is this one is a bare metal system in a data center I can't touch. The base OS was installed by the data center but is still CentOS 7.9. It is possible the host has something in the network config I have missed but I cannot find it.
The GUI is giving me "Error 530 - Unable to add the host: Cannot find the server resources at http://10.120.10.2"; In the management log I see: Failed to handle host connection: com.cloud.exception.ConnectionException: Incorrect Network setup on agent, Reinitialize agent after network names are setup, details : Can not find network: cloudbr0 I have checked and rechecked the network config on the host. cloudbr0 is there and properly configured as a bridge. All of my communications with the host are via this interface so I know it's up. I've compared settings on the host and in the Physical Network to my working zones and everything matches. The agent.properties file has the correct "cloudbr0" entries as expected (and no extras). The remote system is connected via VPN. I have verified the VPN is fully functional. The new host has the firewall disabled and iptables entries for all the host/agent ports. I've used nmap to verify connectivity between the management server and the host and that the required ports are actually open. The zone, pod and cluster are all correctly added. I manually added secondary NFS storage successfully. I have posted the relevant management and agent logs here. management.log <https://drive.google.com/file/d/1UuiD85rzgrJ9zA9_snhad76CAm1b8BTU/view?usp=sharing> agent.log <https://drive.google.com/file/d/1z9FfeCuHw05R1Zk5Hqr6IIPW8_W5Wr-N/view?usp=sharing> You'll see where I removed the host at the start of the logs then re-add it. On the host side, I cleared relevant agent.properties, deleted the cloud.* key files and restarted the agent prior to this test. I'm still a cloudstack newbie so I totally expect that I missed something or slipped in a typo; but I'm not seeing it. Help and pointers are very appreciated! Regards, Evan
