Hi guys. -> $ ovirt-hosted-engine-cleanup -q says it ran its stuff, done & dusted yet I see 'ovirtmgmt' bridge remains. Would that be a bug and how to clean it? many thanks, L.

Problems provisioning 4.4.6 hosted engine
by Sketch 23 May '21

23 May '21

This is a new system is CentOS 8.3, with the oVirt-4.4 repo and all updates applied. When I try to install the hosted engine with my engine backup from 4.3.10, the installation fails with a too many open files error. My 8.3 hosts already had 1M system max files, which is more than any of my CentOS 7/oVirt 4.3 hosts have. I tried increasing it to 2M with no luck, so my suspicion is that the error is on the engine itself? I tried provisioning a new engine just to test, and I get SSH key errors instead of this one. Any suggestions? 2021-05-12 23:09:44,731-0700 ERROR ansible failed { "ansible_host": "localhost", "ansible_playbook": "/usr/share/ovirt-hosted-engine-setup/ansible/trigger_role.yml", "ansible_result": { "_ansible_no_log": false, "exception": "Traceback (most recent call last):\n File \"/usr/lib/python3.6/site-packages/ansible/executor/task_executor.py\", line 665, in _execute\n result = self._handler.run(task_vars=variables)\n File \"/usr/lib/python3.6/site-packages/ansible/plugins/action/wait_for_connection.py\", line 122, in run\n self._remove_tmp_path(self._connection._shell.tmpdir)\n File \"/usr/lib/python3.6/site-packages/ansible/plugins/action/__init__.py\", line 417, in _remove_tmp_path\n tmp_rm_res = self._low_level_execute_command(cmd, sudoable=False)\n File \"/usr/lib/python3.6/site-packages/ansible/plugins/action/__init__.py\", line 1085, in _low_level_execute_command\n rc, stdout, stderr = self._connection.exec_command(cmd, in_data=in_data, sudoable=sudoable)\n File \"/usr/lib/python3.6/site-packages/ansible/plugins/connection/ssh.py\", line 1191, in exec_command\n cmd = self._build_command(*args)\n File \"/usr/lib/python3.6/site-packages/ansible/plugins/connection/s sh.py\", line 562, in _build_command\n self.sshpass_pipe = os.pipe()\nOSError: [Errno 24] Too many open files\n\nDuring handling of the above exception, another exception occurred:\n\nTraceback (most recent call last):\n File \"/usr/lib/python3.6/site-packages/ansible/executor/task_executor.py\", line 147, in run\n res = self._execute()\n File \"/usr/lib/python3.6/site-packages/ansible/executor/task_executor.py\", line 673, in _execute\n self._handler.cleanup()\n File \"/usr/lib/python3.6/site-packages/ansible/plugins/action/__init__.py\", line 128, in cleanup\n self._remove_tmp_path(self._connection._shell.tmpdir)\n File \"/usr/lib/python3.6/site-packages/ansible/plugins/action/__init__.py\", line 417, in _remove_tmp_path\n tmp_rm_res = self._low_level_execute_command(cmd, sudoable=False)\n File \"/usr/lib/python3.6/site-packages/ansible/plugins/action/__init__.py\", line 1085, in _low_level_execute_command\n rc, stdout, stderr = self._connection.exec_command (cmd, in_data=in_data, sudoable=sudoable)\n File \"/usr/lib/python3.6/site-packages/ansible/plugins/connection/ssh.py\", line 1191, in exec_command\n cmd = self._build_command(*args)\n File \"/usr/lib/python3.6/site-packages/ansible/plugins/connection/ssh.py\", line 562, in _build_command\n self.sshpass_pipe = os.pipe()\nOSError: [Errno 24] Too many open files\n", "msg": "Unexpected failure during module execution.", "stdout": "" }, "ansible_task": "Wait for the local VM", "ansible_type": "task", "status": "FAILED", "task_duration": 3605 }

Import to VMware
by Darin Schmidt 21 May '21

21 May '21

Hello, Ive exported an OVA of a server we had made on OVIRT and Im trying to import it to VMware. Its complaining that the ovf:format is incorrect. ovf:format="http://www.gnome.org/~markmc/qcow-image-format.html" That link doesnt resolve to anywhere because it appears its now http://people.gnome.org/~markmc/qcow-image-format.html But I dont know whats supposed to go there nor have I been able to locate anything to help solve this issue. All I really need is access to the files in the, what I assume is, vdmk file that comes along with the ovf file, which mine is called: 154b3d77-d340-4d24-a448-66265c5fb613 So if anything, is there a way to open this vm disk so I can gain access to the files? Thanks

Error Adding host to cluster
by David Johnson 20 May '21

20 May '21

When I attempt to install a new host to my cluster from the GUI I get this set of errors/warnings, and the install fails. - Host has no default route - The Host CPU does not match the Cluster CPU Tye and is running in a degraded mode. It is missing the following CPU flags: vmx, model_Cascadelake-Server-noTSX. The new host has a brand new bare centos 8 installation on it. It successfully installed from the internet. The *new host* hardware is 48x Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz The *pre-existing host* is 64x Intel(R) Xeon(R) Silver 4216 CPU @ 2.10GHz If I am reading the ansible logs correctly, ansible is failing to find the *ovirt-hosted-engine-setup* package, which is confusing since I have a separate physical machine for the engine (which I am using to install from), and don't want a self hosted engine. Any advice would be welcome. --- Ansible logs from the most recent failed installation attempt: 2021-05-14 20:18:04,949 - runner_service.services.playbook - DEBUG - cb_event_handler event_data={'uuid': 'fa961926-9a3a-4d9e-a6bf-d53f98645af2', 'counter': 52, 'stdout': 'fatal: [ ovirt-host-04.maxisinc.net] FAILED! => {"changed": false, "failures": ["No package ovirt-hosted-engine-setup available."], "msg": "Failed to install some of the specified packages", "rc": 1, "results": []}', 'start_line': 44, 'end_line': 45, 'runner_ident': '6060ba26-b51b-11eb-ba6e-d8cb8a87894e', 'event': 'runner_on_failed', 'pid': 1742807, 'created': '2021-05-15T01:18:04.947870', 'parent_uuid': 'd8cb8a87-894e-e341-1e1c-0000000001a1', 'event_data': {'playbook': 'ovirt-host-deploy.yml', 'playbook_uuid': 'e5595457-2c74-4525-8d98-e34bf2e0e342', 'play': 'all', 'play_uuid': 'd8cb8a87-894e-e341-1e1c-000000000007', 'play_pattern': 'all', 'task': 'Install ovirt-hosted-engine-setup package', 'task_uuid': 'd8cb8a87-894e-e341-1e1c-0000000001a1', 'task_action': 'yum', 'task_args': '', 'task_path': '/usr/share/ovirt-engine/ansible-runner-service-project/project/roles/ovirt-host-deploy-vdsm/tasks/packages.yml:6', 'role': 'ovirt-host-deploy-vdsm', 'host': 'ovirt-host-04.maxisinc.net', 'remote_addr': 'ovirt-host-04.maxisinc.net', 'res': {'msg': 'Failed to install some of the specified packages', 'failures': ['No package ovirt-hosted-engine-setup available.'], 'results': [], 'rc': 1, 'invocation': {'module_args': {'name': ['ovirt-hosted-engine-setup'], 'state': 'present', 'allow_downgrade': False, 'autoremove': False, 'bugfix': False, 'disable_gpg_check': False, 'disable_plugin': [], 'disablerepo': [], 'download_only': False, 'enable_plugin': [], 'enablerepo': [], 'exclude': [], 'installroot': '/', 'install_repoquery': True, 'install_weak_deps': True, 'security': False, 'skip_broken': False, 'update_cache': False, 'update_only': False, 'validate_certs': True, 'lock_timeout': 30, 'conf_file': None, 'disable_excludes': None, 'download_dir': None, 'list': None, 'releasever': None}}, '_ansible_no_log': False, 'changed': False}, 'start': '2021-05-15T01:18:03.800468', 'end': '2021-05-15T01:18:04.947696', 'duration': 1.147228, 'ignore_errors': None, 'event_loop': None, 'uuid': 'fa961926-9a3a-4d9e-a6bf-d53f98645af2'}} 2021-05-14 20:18:04,951 - runner_service.services.playbook - DEBUG - cb_event_handler event_data={'uuid': '1007f755-dee8-407f-999c-b08c8b813ea7', 'counter': 53, 'stdout': '\r\nPLAY RECAP *********************************************************************\r\ novirt-host-04.maxisinc.net : ok=14 changed=1 unreachable=0 failed=1 skipped=2 rescued=0 ignored=0 \r\n', 'start_line': 45, 'end_line': 49, 'runner_ident': '6060ba26-b51b-11eb-ba6e-d8cb8a87894e', 'event': 'playbook_on_stats', 'pid': 1742807, 'created': '2021-05-15T01:18:04.949918', 'parent_uuid': 'e5595457-2c74-4525-8d98-e34bf2e0e342', 'event_data': {'playbook': 'ovirt-host-deploy.yml', 'playbook_uuid': 'e5595457-2c74-4525-8d98-e34bf2e0e342', 'changed': {' ovirt-host-04.maxisinc.net': 1}, 'dark': {}, 'failures': {' ovirt-host-04.maxisinc.net': 1}, 'ignored': {}, 'ok': {' ovirt-host-04.maxisinc.net': 14}, 'processed': {'ovirt-host-04.maxisinc.net': 1}, 'rescued': {}, 'skipped': {'ovirt-host-04.maxisinc.net': 2}, 'artifact_data': {}, 'uuid': '1007f755-dee8-407f-999c-b08c8b813ea7'}} 2021-05-14 20:18:05,147 - runner_service.services.playbook - INFO - Playbook ovirt-host-deploy.yml, UUID=6060ba26-b51b-11eb-ba6e-d8cb8a87894e ended, status=failed 2021-05-14 20:18:05,154 - runner_service.services.playbook - INFO - Playbook ovirt-host-deploy.yml Stats: {'skipped': {' ovirt-host-04.maxisinc.net': 2}, 'ok': {'ovirt-host-04.maxisinc.net': 14}, 'dark': {}, 'failures': {'ovirt-host-04.maxisinc.net': 1}, 'processed': {' ovirt-host-04.maxisinc.net': 1}, 'changed': {'ovirt-host-04.maxisinc.net': 1}} *David Johnson*

vmfex in 4.4.7
by Michal Skrivanek 20 May '21

20 May '21

Hi there, just a heads up that in 4.4.7 we’ll be removing vdsm’s hard dependency on VM-FEX hook. The functionality has been more or less obsoleted by SR-IOV and its usage is minimal these days. With the upgrade the vdsm-hook-vmfex-dev rpm will get automatically uninstalled. If you happen to use it and it works well for you then please "dnf install" it after the upgrade. There is no change in functionality and the hook is not going away, it’s just that in order to not make it mandatory from now on, it gets removed during "dnf upgrade”. Thanks, michal

How to create new users other than admin
by gaurav.gohan＠gmail.com 20 May '21

20 May '21

Hello everyone, I am new to ovirt and would like to apologise if this has been asked before. When I created a cluster of ovirt 4.3, I was presented with the option of creating an admin user. However, we would like to assign different login credentials for our employees with different set of rules. I was able to view the users menu under the Administration > Users. Currently we only have an admin user with internal-authz. When clicking on the add button, I only see "internal-authz" and "*" under namespace. Clicking on Go button simply shows admin user again. I created a new role under the Administration > Configure > Roles, however, there is no option to add new user anywhere. Can you please point me to the right steps for adding new users? Thanks
