Hi Cristian, The exception you are seeing is most likely to happen if the systemvm.iso hasn't been injected with the Management server's key. One way to validate it, would be to go to your secondary store - I presume you are working on a VMware setup - mount the systemvm-4.15.2.iso and verify the authorized_keys data with what's present on the MS at /var/cloudstack/management/.ssh/id_rsa.pub.

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 .
