Issues with snapshot and template
by David Johnson 06 Oct '22

06 Oct '22

Good morning all, Thank you in advance. My current environment is ovirt 4.5.2.4-1.el8, running on centos 7.9. I'm looking for advice on resolving two issues that have just come to light: *Issue #1*: When I attempt to create a template from the oVirt GUI, I click the "Make Template" button, enter the name for the new template, then click the "OK" button. The OK button highlights, but nothing happens. *There are no entries showing activity in the engine.log.* *Issue #2:* When I delete a snapshot, after the snapshot is deleted, I receive this error message from the GUI: [image: image.png] *ui.log entry:* 2022-10-05 11:01:42,014-05 ERROR [org.ovirt.engine.ui.frontend.server.gwt.OvirtRemoteLoggingService] (default task-243) [] Permutation name: 872EE01DC49AC3F81586694F1584D19D 2022-10-05 11:01:42,014-05 ERROR [org.ovirt.engine.ui.frontend.server.gwt.OvirtRemoteLoggingService] (default task-243) [] Uncaught exception: com.google.gwt.core.client.JavaScriptException: (TypeError) : Cannot read properties of null (reading 'wV') at org.ovirt.engine.ui.uicommonweb.models.vms.VmSnapshotListModel.$updateActionAvailability(VmSnapshotListModel.java:834) at org.ovirt.engine.ui.uicommonweb.models.vms.VmSnapshotListModel.onSelectedItemChanged(VmSnapshotListModel.java:262) at org.ovirt.engine.ui.uicommonweb.models.SearchableListModel.$setItems(SearchableListModel.java:714) at org.ovirt.engine.ui.uicommonweb.models.vms.VmSnapshotListModel.$updateItems(VmSnapshotListModel.java:225) at org.ovirt.engine.ui.uicommonweb.models.vms.VmSnapshotListModel.setItems(VmSnapshotListModel.java:205) at org.ovirt.engine.ui.uicommonweb.models.SearchableListModel$SetItemsAsyncQuery$1.$onSuccess(SearchableListModel.java:878) at org.ovirt.engine.ui.uicommonweb.models.SearchableListModel$SetItemsAsyncQuery$1.onSuccess(SearchableListModel.java:878) at org.ovirt.engine.ui.frontend.Frontend$1.$onSuccess(Frontend.java:239) at org.ovirt.engine.ui.frontend.Frontend$1.onSuccess(Frontend.java:239) at org.ovirt.engine.ui.frontend.communication.OperationProcessor$1.$onSuccess(OperationProcessor.java:133) at org.ovirt.engine.ui.frontend.communication.OperationProcessor$1.onSuccess(OperationProcessor.java:133) at org.ovirt.engine.ui.frontend.communication.GWTRPCCommunicationProvider$5$1.$onSuccess(GWTRPCCommunicationProvider.java:270) at org.ovirt.engine.ui.frontend.communication.GWTRPCCommunicationProvider$5$1.onSuccess(GWTRPCCommunicationProvider.java:270) at com.google.gwt.user.client.rpc.impl.RequestCallbackAdapter.onResponseReceived(RequestCallbackAdapter.java:198) at com.google.gwt.http.client.Request.$fireOnResponseReceived(Request.java:233) at com.google.gwt.http.client.RequestBuilder$1.onReadyStateChange(RequestBuilder.java:409) at Unknown.eval(webadmin-0.js) at com.google.gwt.core.client.impl.Impl.apply(Impl.java:306) at com.google.gwt.core.client.impl.Impl.entry0(Impl.java:345) at Unknown.eval(webadmin-0.js) *David Johnson*

oVirt 4.5.2 /var growing rapidly due to ovirt_engine_history db
by sohail_akhter3＠hotmail.com 05 Oct '22

05 Oct '22

Hi, We have recently upgrade our oVirt environment to 4.5.2 version. Environment is based on hosted-engine. Since we have upgrade we noticed rapid incrase in /var partition in engine VM. It is increasing very rapidly. If we vacuum ovirt_engine_history db, /var size reduces but next day size will increase again upto 5-10%. We did db vacuuming couple of time but not sure we it is increasing so rapidly. Here is the partial output of vacuuming that was done on 26-08-22. Table "host_interface_hourly_history" had more entries to be removed. Rest of the table had not much entries. Previously table "host_interface_samples_history" had entries to be removed. Any Idea what can be the reason for that? # dwh-vacuum -f -v SELECT pg_catalog.set_config('search_path', '', false); vacuumdb: vacuuming database "ovirt_engine_history" RESET search_path; SELECT c.relname, ns.nspname FROM pg_catalog.pg_class c JOIN pg_catalog.pg_namespace ns ON c.relnamespace OPERATOR(pg_catalog.=) ns.oid LEFT JOIN pg_catalog.pg_class t ON c.reltoastrelid OPERATOR(pg_catalog.=) t.oid WHERE c.relkind OPERATOR(pg_catalog.=) ANY (array['r', 'm']) ORDER BY c.relpages DESC; SELECT pg_catalog.set_config('search_path', '', false); VACUUM (FULL, VERBOSE) public.host_interface_samples_history; INFO: vacuuming "public.host_interface_samples_history" INFO: "host_interface_samples_history": found 3135 removable, 84609901 nonremovable row versions in 1564960 pages DETAIL: 0 dead row versions cannot be removed yet. CPU: user: 41.88 s, system: 14.93 s, elapsed: 422.83 s.

TPM device is required by the guest OS Hi, it is a Windows VM, right? It is a bug, I filed https://github.com/oVirt/ovirt-engine/issues/702 . The export should work. A workaround could be temporarily switching the VM operating system in the VM properties to Red Hat Enterprise Linux 9 before exporting but I'm not sure it won't change some other VM properties, be careful if you attempt it. Regards, Milan

Export to Data Domain (with TPM)
by Christopher Law 05 Oct '22

05 Oct '22

Hi - Anyone explain why I can't export a Virtual Machine with a TPM? Is this something to do with the TPM data? I'm exporting the VM to some cold storage. What's the deal here how can I export it and keep the TPM data or do I have to disable TPM on it first? oVirt Error message when trying to export a VM to a Data Domain that has a TPM. Export VM Failed Cannot add VM. TPM device is required by the guest OS Cheers, Chris.

Issue with disk import and disk upload - ovirt 4.5.2
by Proniakin Marcin 04 Oct '22

04 Oct '22

Hello, After upgrading ovirt to version 4.5.2, I've experienced issue with using import function in import disk window in storage domain after attaching it to data center. Logs in the attachment (#1). Second issue is with uploading disks from storage domain window. Using example from attachment (#2): When choosing to upload disk to domain portal-1 from upload function in the storage domain disk window, ovirt chooses wrong data-center dev-1 (dev-1 datacenter has domain dev-1, portal-1 datacenter has domain portal-1) and wrong host to upload. Accepting this upload always fails. When choosing to upload disk from storage -> disks window works fine. Issues confirmed on two independent ovirt servers (both with version 4.5.2).

Local and remote storage
by Murilo Morais 04 Oct '22

04 Oct '22

Good evening everyone. Guys, I have two machines that use oVirt, I managed to put CephFS as a storage domain and everything is working perfectly, but on these two machines there are 4 NVMe on each, I would like to know if there is any possibility or any way to use their local storage? I don't care if the host dies and I don't get the VM up on the other, as it would be for very specific cases, so there's no problem with that.

Creating an oVirt Engine Appliance on a different EL Distro (eg Rocky Linux)
by Matthew J Black 03 Oct '22

03 Oct '22

Hi All, Here's an interesting question: What is the process (ie the Step-By-Step process) to create an/the oVirt Engine Appliance based on another version of EL (ie in my case, Rocky Linux)? Is there a "Manual" somewhere? I mean, surely the oVirt Project's Release Manager has *something* that they follow to create the relevant rpm file - no? Cheers Dulux-Oz
