Hey people, I hope someone can help me identify if there's something I'm doing wrong or if there's a bug. Originally I wanted to re-deploy my self-hosted engine, as it is still on version 4.5.5 with CentOS 8, and therefore can't be updated anymore. To get a fresh backup of the currently running config I did the following: 1. On physical host `hosted-engine --set-maintenance --mode=global` 2. On engine VM `systemctl stop ovirt-engine` and then 3. `engine-backup --scope=all --mode=backup --file=/mnt/ovirt-engine-backup/ovirt-engine-4.5.5-backup.bck --log=/mnt/ovirt-engine-backup/ovirt-engine-4.5.5-backup.log` (where `/mnt/ovirt-engine-backup/` is a NFS share) 4. On physical host `hosted-engine --vm-shutdown` Then I set up a new physical host with CentOS 9 Stream (Build 20250320), enabled and installed the oVirt repository as mentioned at https://www.ovirt.org/download/install_on_rhel.html, then ran: `hosted-engine --deploy --4 --restore-from-file=/mnt/ovirt-engine-backup/ovirt-engine-4.5.5-backup.bck` (of course mounting the NFS share prior to this). But after giving it all the information it needed it fails after 15-20 minutes with several errors in the logfile, which I cannot identify the primary/root cause of. The first error that appears is this one: ``` 2025-03-25 11:19:35,427+0100 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:115 TASK [ovirt.ovirt.hosted_engine_setup : Include after engine-setup custom tasks files for the engine VM] 2025-03-25 11:19:36,730+0100 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:115 TASK [ovirt.ovirt.hosted_engine_setup : Wait for the engine to reach a stable condition] 2025-03-25 11:19:37,431+0100 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:115 skipping: [localhost] 2025-03-25 11:19:38,133+0100 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:115 TASK [ovirt.ovirt.hosted_engine_setup : Configure LibgfApi support] 2025-03-25 11:19:38,835+0100 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:115 skipping: [localhost] 2025-03-25 11:19:39,536+0100 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:115 TASK [ovirt.ovirt.hosted_engine_setup : Save original OvfUpdateIntervalInMinutes] 2025-03-25 11:19:42,041+0100 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:115 changed: [localhost -> 192.168.222.170] 2025-03-25 11:19:42,742+0100 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:115 TASK [ovirt.ovirt.hosted_engine_setup : Set OVF update interval to 1 minute] 2025-03-25 11:19:45,147+0100 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:109 {'changed': True, 'stdout': 'Index 1 out of bounds for length 1', 'stderr': 'Picked up JAVA_TOOL_OPTIONS: -Dcom.redhat.fips=false', 'rc': 1, 'cmd': ['engine-config', '-s', 'OvfUpdateIntervalInMinutes=1'], 'start': '2025-03-25 11:19:43.872322', 'end': '2025-03-25 11:19:44.941216', 'delta': '0:00:01.068894', 'msg': 'non-zero return code', 'invocation': {'module_args': {'_raw_params': 'engine-config -s OvfUpdateIntervalInMinutes=1', '_uses_shell': False, 'stdin_add_newline': True, 'strip_empty_ends': True, 'argv': None, 'chdir': None, 'executable': None, 'creates': None, 'removes': None, 'stdin': None}}, 'stdout_lines': ['Index 1 out of bounds for length 1'], 'stderr_lines': ['Picked up JAVA_TOOL_OPTIONS: -Dcom.redhat.fips=false'], '_ansible_no_log': False, '_ansible_delegated_vars': {'ansible_host': '192.168.222.170', 'ansible_port': None, 'ansible_user': 'root', 'ansible_ connection': 'smart'}} 2025-03-25 11:19:45,248+0100 ERROR otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:113 fatal: [localhost -> 192.168.222.170]: FAILED! => {"changed": true, "cmd": ["engine-config", "-s", "OvfUpdateIntervalInMinutes=1"], "delta": "0:00:01.068894", "end": "2025-03-25 11:19:44.941216", "msg": "non-zero return code", "rc": 1, "start": "2025-03-25 11:19:43.872322", "stderr": "Picked up JAVA_TOOL_OPTIONS: -Dcom.redhat.fips=false", "stderr_lines": ["Picked up JAVA_TOOL_OPTIONS: -Dcom.redhat.fips=false"], "stdout": "Index 1 out of bounds for length 1", "stdout_lines": ["Index 1 out of bounds for length 1"]} ``` The full log is available here: https://filebin.net/dimi5g2o6q20t4aj I also tried with a completely clean deployment, without restoring from backup (once without and once with using `ovirt-hosted-engine-cleanup` in between). The errors in the log are completely the same. Also I tried to use the oVirt Node master experimental ISO (`ovirt-node-ng-installer-4.5.6-2025031111.c9s.iso`), same issue. Does the problem lie somewhere in my answers for the questions asked by the tool? I cannot identify giving any wrong info. Can someone maybe reproduce the issue?
