Cannot ping from a nested VM
by wodel youchi 23 Dec '20

23 Dec '20

Hi, We have an HCI plateforme based upon 4.4.3 version. We activated the use of nested kvm and we reinstalled all the nodes to be able to use it. Then we created a new nested HCI on top of the physical HCI to test ansible deployment. The deployment went well until the phase which adds the two other nodes (the two other virtualized hypervisors), but the VM-Manager couldn't add them. After investigation, we found that the nested VM-Manager could not communicate except with it's first virtualized hypervisor. To make the nested VM-Manager capable of communicating with the outside world, we had to stop firewalld on the physical node of the HCI. Any ideas?

Upgrade to 4.4.4
by Jonathan Baecker 22 Dec '20

22 Dec '20

Hello, I'm running here a upgrade from 4.4.3 to latest 4.4.4, on a 3 node self hosted cluster. The engine upgrade went fine and now I'm on host upgrades. When I check there the updates it shows only *ovirt-node-ng-image-update-4.4.4-1.el8.noarch.rpm*. For that I have run manual updates on each host, with maintenance mode -> yum update -> reboot. When I run now on the engine *cat /etc/redhat-release *it show: *CentOS Linux release 8.3.2011* But on my nodes it shows still: *CentOS Linux release 8.2.2004 (Core)* How can this be? Best regards Jonathan

Is there a way to properly migrate an oVirt cluster from one network to another properly? Especially when it comes to the self-hosted manager and its storage. -- Kristian Petersen System Administrator BYU Dept. of Chemistry and Biochemistry

OVA export issues
by Jonathan Baecker 20 Dec '20

20 Dec '20

Hello, I have here an older server, one host with external engine, 4.4.4-1.el8 installation, with a slow 2Gbit nfs storage. When I export OVAs from smaller VMs (under 40GB) it works but with bigger one, around 95GB I have problems. I have already change the export target to a local folder, which makes the process faster and the GUI shows no errors, but when I extract the vm.ovf file, from the exported archive, it is not complete. It missing a closing part from the xml definition. The end stops here: *</ovf:E* By my test before, I was able to add the closing part by hand and import the OVA, but then the VM had no disk attached. I don't know if the size is the problem, my backup script which export the VMs to the export domain works normal. I only know, that the error I can reproduce on minimum 2 VMs. The last part of the export log looks like: /var/log/ovirt-engine/ansible-runner-service.log:2020-12-19 12:02:52,610 - runner_service.services.playbook - DEBUG - cb_event_handler event_data={'uuid': '2ac62a85-7efa-4d14-a941-c1880bd016fd', 'counter': 35, 'stdout': 'changed: [onode-2.example.org]', 'start_line': 34, 'end_line': 35, 'runner_ident': '9ac880ce-4219-11eb-bfd8-5254000e4c2c', 'event': 'runner_on_ok', 'pid': 1039034, 'created': '2020-12-19T17:02:52.606639', 'parent_uuid': '5254000e-4c2c-ed4e-fdf7-000000000022', 'event_data': {'playbook': 'ovirt-ova-export.yml', 'playbook_uuid': 'ee4a698c-f639-49c8-8fa9-af2778f0862d', 'play': 'all', 'play_uuid': '5254000e-4c2c-ed4e-fdf7-000000000007', 'play_pattern': 'all', 'task': 'Rename the OVA file', 'task_uuid': '5254000e-4c2c-ed4e-fdf7-000000000022', 'task_action': 'command', 'task_args': '', 'task_path': '/usr/share/ovirt-engine/ansible-runner-service-project/project/roles/ovirt-ova-export-post-pack/tasks/main.yml:2', 'role': 'ovirt-ova-export-post-pack', 'host': 'onode-2.discovery.intern', 'remote_addr': 'onode-2.discovery.intern', 'res': {'cmd': ['mv', '/mnt/intern/win2016-01.ova.tmp', '/mnt/intern/win2016-01.ova'], 'stdout': '', 'stderr': '', 'rc': 0, 'start': '2020-12-19 12:02:52.560917', 'end': '2020-12-19 12:02:52.572358', 'delta': '0:00:00.011441', 'changed': True, 'invocation': {'module_args': {'_raw_params': 'mv "/mnt/intern/win2016-01.ova.tmp" "/mnt/intern/win2016-01.ova"', 'warn': True, '_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': [], 'stderr_lines': [], '_ansible_no_log': False}, 'start': '2020-12-19T17:02:51.954144', 'end': '2020-12-19T17:02:52.605820', 'duration': 0.651676, 'event_loop': None, 'uuid': '2ac62a85-7efa-4d14-a941-c1880bd016fd'}} Any ideas?

can someone help me try to assign gluster network this is my current setup hosted-engine with stand alone gluster ovirt host 1 host 2 host 3 (and so on) eno1 192.168.0.10 ovirtmgmt enfs20 vm network dmz_1 dmz_2 dmz3 (and so on) enfs21 <--- i want to assign this physical network with gluster netowrk gluster1 gluster 2 (and so on) eno1 192.168.0.11 eno2 i followed the instruction in the offical documentation Create the logical network for gluster traffic Log in to the engine Browse to the engine and log in using the administrative credentials you configured in Chapter 8, Deploy the Hosted Engine using the Cockpit UI. Create a logical network for gluster traffic Click the Networks tab and then click New. The New Logical Network wizard appears. On the General tab of the wizard, provide a Name for the new logical network, and uncheck the VM Network checkbox. On the Cluster tab of the wizard, uncheck the Required checkbox. Click OK to create the new logical network. Enable the new logical network for gluster Click the Networks tab and select the new logical network. Click the Clusters sub-tab and then click Manage Network. The Manage Network dialogue appears. In the Manage Network dialogue, check the Migration Network and Gluster Network checkboxes. Click OK to save. Attach the gluster network to the host Click the Hosts tab and select the host. Click the Network Interfaces subtab and then click Setup Host Networks. Drag and drop the newly created network to the correct interface. Ensure that the Verify connectivity checkbox is checked. Ensure that the Save network configuration checkbox is checked. Click OK to save. so when i got to network> then click the logical network i create (gluster_net) cluster tab > network status is down? then click manage network button and assign migration network and gluster network
