Hello,
I was not able to fix this error "Failed to authentication SSH" and looks like a bug for me, I will explain here why. My setup before adding new ZONE: 1. Cloudstack 4.15.2 + VMware 6.5 with 1 Basic Network Zone. ( This is an old setup, it was upgraded frequently, I think from 4.2 ) 2. I add new VMware zone, but this one with Advanced Networking, I end with this repetitive error and nothing else. 3. I decide to add a new zone, the same as I have at (2) with Advanced Networking, everything works perfect, no issue at systemvm deploy, routers, instances. 4. I delete the zone from point (2) 5. I add again the same zone, end with the same error. I have tried multiple things, delete the template, add again, inject, nothing works, I end with the same error, over and over, and I do not see the why. 021-09-23 11:53:54,666 ERROR [c.c.h.v.r.VmwareResource] (DirectAgent-228:ctx-083b9265 lnd-uk-002.test.host, job-35231/job-35263, cmd: SetupKeyStoreCommand) (logid:df4131be) Command failed due to Exception: java.lang.Exception Message: Failed to authentication SSH user root on host 10.15.0.204 2021-09-23 11:53:54,674 ERROR [c.c.v.VirtualMachineManagerImpl] (Work-Job-Executor-19:ctx-808054ab job-35231/job-35263 ctx-eb7c37bb) (logid:df4131be) Retrying after catching exception while trying to secure agent for systemvm id=2025 com.cloud.utils.exception.CloudRuntimeException: Unable to read/process CSR: Command failed due to Exception: java.lang.Exception Message: Failed to authentication SSH user root on host 10.15.0.204 Here is the full log : https://pastebin.com/raw/fFfmquVB Maybe someone have a hint for me .
