by Pascal D 26 May '21

26 May '21

I am unable to create disk using JSON however the same query in XML works great. In Json I get the following message back: { "detail": "For correct usage, see: https://ov1.butterflyit.com/ovirt-engine/apidoc#services/disks/methods/add", "reason": "Request syntactically incorrect." } Both use POST /ovirt-engine/api/disks and the content-type is either application/json or application/xml Here is the request in JSON: { "id": "866770c3-acf9-4f67-b72c-05ed241908e4", "name": "mydisk", "description": "test disk", "bootable": false, "shareable": true, "provisioned_size": 10240000000, "interface": "virtio", "format": "cow", "storage_domains": { "storage_domain": { "name": "VMS" } } } And here it is in XML <disk id="866770c3-acf9-4f67-b72c-05ed241908e4"> <bootable>false</bootable> <name>mydisk</name> <description>test Drive</description> <interface>virtio</interface> <provisioned_size>10240000000</provisioned_size> <format>cow</format> <storage_domains> <storage_domain> <name>VMS</name> </storage_domain> </storage_domains> </disk>

Ovirt 4.4.6.8 High Performance VM quirkiness
by Don Dupuis 26 May '21

26 May '21

I created a high performance vm and everything is fine. I stop the virtual machine and make edits to it and again runs correctly. I shutdown the vm and click the edit tab to look at what I changed and it is now back to the defaults and my edits are gone. Is this now the intended result. I was using the same settings in 4.3 and never exhibited this behavior. What I have observed so for is that I disabled Headless, disabled cpu pinning, and changed numa config. When I shutdown the vm, they revert to default of Headless enabled, cpu pinning is set and the numa config changed. This is not what I expect to happen. Has anyone else noticed this behavior? Thanks Don

CPU Compatibility Problem after Upgrading Centos 8 Stream Host
by Nur Imam Febrianto 25 May '21

25 May '21

Hi, This morning I have a problem that suddenly my Host (Using Centos 8 Stream, not oVirt Node) showing error with Cpu Compatibility. It says my CPU doesn’t have Haswell-noTSX and spec_ctrl flag. After downgrading the kernel back from 4.18.0 – 305 to 4.18.0 – 301.1 and rollback yum update, it working again. Do anybody having same issue ? I’m using Xeon E5-2695v4 with cluster compatibility Secure Intel Haswell. Using oVirt 4.4.6 on CentOS Stream host. Thanks before.

Cluster stuck in maintenance - Hosts not upgrading as expected
by David White 24 May '21

24 May '21

I have a 3-node hyperconverged cluster with Gluster filesystem running on RHEL 8.3 hosts. It's been stable on oVirt 4.5. Today, I just upgraded the Engine to v4.6. [Screenshot from 2021-05-22 20-29-23.png] I then logged into the oVirt manager, navigated to Compute -> Clusters, and clicked on Upgrade. The Status of the cluster does have an exclamation mark that says "Upgrade Cluster Compatibility Level", but my understanding is, I shouldn't do that until all 3 of my hosts have been upgraded. Looking at active tasks, I see that the first host in my cluster is stuck in "Upgrading". It's now been like this for 3 hours, without any visible progress. If I try to launch a VM that is not configured for high availability, the VM fails to launch, and I get a message about the cluster being in "Maintenance Mode" and that none of the hosts satisfies current scheduling restraints. How do I.... a) Cancel / clear the upgrade and take the cluster out of "maintenance mode" b) Properly upgrade the cluster, since clicking the "Upgrade" button clearly didn't work?

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 }
