EXPECTED RESULTS

ACTUAL RESULTS

I am using 4.19 version on cloudstack management and cloudstack host server. But, I am unable to add the host server to management server. Both are Ubuntu 22.04 server.
 Getting the following error:

---
Error 530
Unable to add the host: Cannot find the server resources at http://192.168.200.238
---

Able to get ping response from host and management server:

Could you please take look at the /var/log/cloudstack/management/management-server.log for any other exceptions

and can you provide the log to investigate further

Please check and let me know any further details needed.

[subincb30]

Additionally, I found that the port 8250 is not listening in my cloudstack host server.

[weizhouapache]

the logs show

2024-09-19 07:24:55,064 DEBUG [c.c.h.k.d.LibvirtServerDiscoverer] (qtp341748265-16:ctx-d80d59ca ctx-6dbc68fe) (logid:4e450a45) Succeeded to import certificate in the keystore for agent on the KVM host: 192.168.200.238. Agent secured and trusted.

there should be some errors in log like CloudStack Agent setup through command ... failed

[subincb30]

@weizhouapache Sorry I didn't get your point. Also, I couldn't find any errors related to the cloud stack agent on the cloud stack management-server.log.

[weizhouapache]

@weizhouapache Sorry I didn't get your point. Also, I couldn't find any errors related to the cloud stack agent on the cloud stack management-server.log.

the logs shows the mgmt server has connected to the host and configured security (for cloudstack-agent and libvirt). so it is not a connectivity issue.

please upload the full log by keyword ctx-6dbc68fe if possible.

can you upload the file /var/log/cloudstack/agent/setup.log on the kvm host ?

@subincb30
have you configured cloudbr0 on the kvm host ?

[subincb30]

Can you give me complete guide for that? I got some doc for for that but it was not clear. But, I found one new network interface in my server.
