Reinstall without dataloss
by hans＠jiflin.nl 02 Oct '21

02 Oct '21

Hi all, I am new here, been searching the mailing list on a regular base when I encountered problems and till now I always was able to keep the system up & running. As said... till now... I have oVirt at home, and I have about 7 vm's running on it. Lately I have had some troubles with my electricity, which results in a complete power outage on a irregular base. Yesterday I had a power outage which left the system unbootable with the following errors: error: ../../grub-core/loader/i386/pc/linux.c:170:invalid magic number. error: ../../grub-core/loader/i386/pc/linux.c:1418:you need to load the kernel first. Press any key to continue Normally this can be solved following https://access.redhat.com/solutions/5829141, but his time also the files in /boot had a size of 0 bytes. So basically i did not have a working kernel on the system anymore. https://www.thegeekdiary.com/centos-rhel-7-how-to-install-kernel-from-rescu… does work for CentOS 8 also, but the ovirt 4.8 iso does not have the same directory structure. Using CentOS 8 installs a kernel, but not a bootable system. Is there a way i can start the installer in troubleshooting mode so I can reinstall just the kernel on the system?

about the expiration time of the oVirt certs
by Tommy Sway 01 Oct '21

01 Oct '21

As you know, there are many kinds of certificates in Ovirt, used for communication, authentication and so on. However, in practice, there is a security risk related to the above certificates. That is, you need to generate a new certificate after the certificate expires. Otherwise, a problem will occur. In addition, different certificates expire at different times, which brings a lot of management trouble to users. Especially in the production system, a huge virtualization cluster may run thousands of VMS. If a cluster certificate has a problem, the impact is very serious. So I felt there was an urgent need for a technical tool that could help users quickly locate certificates, identify their expiration dates, and rebuild them. Even if there is no tool, there should be a way to solve the problems caused by partial certificate expiration. I think it should include the following points: First, how to list the certificate in detail Second, how to check the certificate expiration time Third, how to rebuild the certificate Does anyone else have this kind of confusion? What's a good solution? Thanks.

Using third-party certificate: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
by nicolas＠devels.es 01 Oct '21

01 Oct '21

Hi, I'm making a bare metal oVirt installation, version 4.4.8. 'ovirt-engine' command ends well, however, we're using a third-party certificate (from LetsEncrypt) both for the apache server and the ovirt-websocket-proxy. So we changed configuration files regarding httpd and ovirt-websocket-proxy. Once changed the configurations, if I try to log in to the oVirt engine, I get a "PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target" error. In prior versions we used to add the chain to the /etc/pki/ovirt-engine/.truststore file, however, simply listing the current certificates seems not to be working on 4.4.8. # LANG=C keytool -list -keystore /etc/pki/ovirt-engine/.truststore -alias intermedia_le -storepass mypass keytool error: java.io.IOException: Invalid keystore format Is there something I'm missing here? Thank

Balancing actions not shown in events list
by Gianluca Cecchi 01 Oct '21

01 Oct '21

Hello, I have a cluster composed of 4 hosts, with 2 hosts in site A and 2 hosts in site B. Version of engine and hosts is latest 4.4.8-6. Site A is the primary site and its hosts have SPM priority high, while site B hosts have SPM priority low. For critical VMs I create a cluster affinity group so that they preferably run on hosts in site A. If I migrate a VM from one host in site A to one host in site B, the migration completes but suddenly, after a few seconds (ranging from 10 to 30) the VM comes back again (live migrates) to one host of the site A pool. Two considerations: . when the VM comes back to site A and I'm connected to the web admin gui I see in bottom right the pop-up message regarding the balancing operation: https://drive.google.com/file/d/1lfm0AVwYKyyRL1qHh94AySpr3XAtV7lO/view?usp=… But then if I go in the VM, or cluster, or general events pane I don't see any direct feedback regarding this balancing that took place. I only see the VM migration events: Oct 1, 2021, 2:47:01 PM Migration completed (VM: impoldsrvdbpbi, Source: xxxx, Destination: yyyy, Duration: 15 seconds, Total: 27 seconds, Actual downtime: 67ms) Oct 1, 2021, 2:46:34 PM Migration initiated by system (VM: impoldsrvdbpbi, Source: xxxx, Destination: yyyy, Reason: Affinity rules enforcement). Oct 1, 2021, 2:45:45 PM Migration completed (VM: impoldsrvdbpbi, Source: yyyy, Destination: xxxx, Duration: 2 seconds, Total: 14 seconds, Actual downtime: (N/A)) Oct 1, 2021, 2:45:30 PM Migration started (VM: impoldsrvdbpbi, Source: yyyy, Destination: xxxx, User: gian@internal). That indeed contain some information (Reason: Affinity rules enforcement) but only in the VM migration line. Could it be useful to add an independent line regarding the balancing trigger that implies then a migration? . In this case could it be useful to give the user a warning that the VM will be suddenly migrated back so that he/she can think about it before having at the end two migrations with a final stage that is the starting point itself...? If I leave only one host in site A and put it into maintenance, the VMs are correctly migrated to hosts in site B and even when the host in site A comes back available, the coming back operation is not triggered. Is this something expected or should the live migrate to hosts in site A? Thanks, Gianluca

[Rest API] How to get server user from "permissions"?
by ovirt.org＠nevim.eu 30 Sep '21

Hello, please how to get server user from "permissions"? I try this, but does not working: https://ovirt.localhost/ovirt-engine/api/vms/4ekb93a4-64c6-4b13-9927-8f37f2… I need: Show the server user. This means: Find the user ID of a specific server that is in the role with ID: 00000000-0000-0000-0001-000000000001 Thanks for advice.

Intermittent failure to upload ISOs
by aclysma＠gmail.com 30 Sep '21

30 Sep '21

This may be the same issue as described here: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/CJISJIDQKSINIJ… https://bugzilla.redhat.com/show_bug.cgi?id=1977276 I am on 4.4.8.6-1.el8, installed a couple days ago from the ovirt node ISO. In particular, I noticed if I SSH into the hosted engine and tail -f /var/log/ovirt-imageio/daemon.log, in the failure case I get something like: 2021-09-30 08:15:52,330 INFO (Thread-8) [http] OPEN connection=8 client=::ffff:192.168.1.53 2021-09-30 08:16:23,315 INFO (Thread-8) [http] CLOSE connection=8 client=::ffff:192.168.1.53 [connection 1 ops, 30.984947 s] [dispatch 1 ops, 0.000097 s] No activity in tail -f /var/log/ovirt-imageio/daemon.log on the host (I only have one host) in the failure case, just the engine. In the success case, there is activity in both logs. It is very intermittent. Sometimes uploads work most of the time (maybe 4 out of 5), and I've had other times that uploads do not work at all (0 out of 5). I think when it's behaving particularly badly, restarting the engine (hosted-engine --vm-shutdown, then hosted-engine --vm-start) helps, but I haven't figured out a reliable pattern. (I am logged in as admin.) I've tried several browsers, closing/reopening the browser, etc. Hoping this info will help in tracking it down.

Host reboots when network switch goes down
by cen 29 Sep '21

29 Sep '21

Hi, we are experiencing a weird issue with our Ovirt setup. We have two physical hosts (DC1 and DC2) and mounted Lenovo NAS storage for all VM data. They are connected via a managed network switch. What happens is that if switch goes down for whatever reason (firmware update etc), physical host reboots. Not sure if this is an action performed by Ovirt but I suspect it is because connection to mounted storage is lost and it performs some kind of an emergency action. I would need to get some direction pointers to find out a) who triggers the reboot and why c) a way to prevent reboots by increasing storage? timeouts Switch reboot takes 2-3 minutes.

Ovirt 4.3 Upload of Image fails
by Mark Morgan 29 Sep '21

29 Sep '21

Hi, I am trying to upload an image to a Ovirt 4.3 Instance but it keeps failing. After a few seconds it says paused by system. The test connection is successful in the upload image window so we have installed the certificate properly. Due to an older thread(https://www.mail-archive.com/users@ovirt.org/msg50954.html) I also checked if it has something to do with wifi. But I am not even using a wifi connection. Here is a small part of the log, where you can see the transfer failing. 2021-09-29 11:44:43,011+02 INFO [org.ovirt.engine.core.bll.storage.disk.image.TransferImageStatusCommand] (default task-96804) [d370a18b-bb12-4992-9fc8-7ce6607358f8] Running command: TransferImageStatusCommand internal: false.

Failed to update OVF disks / Failed to update VMs/Templates OVF data for Storage Domain
by nicolas＠devels.es 29 Sep '21

29 Sep '21

Hi, We upgraded from oVirt 4.3.8 to 4.4.8 and sometimes we're finding events like these in the event log (3-4 times/day): Failed to update OVF disks 77818843-f72e-4d40-9354-4e1231da341f, OVF data isn't updated on those OVF stores (Data Center KVMRojo, Storage Domain pv04-003). Failed to update VMs/Templates OVF data for Storage Domain pv02-002 in Data Center KVMRojo. I found [1], however, it seems not to solve the issue. I restarted all the hosts and we're still getting the messages. We couldn't upgrade hosts to 4.4 yet, FWIW. Maybe it's caused by this? If someone could shed some light about this, I'd be grateful. Thanks. [1]: https://access.redhat.com/solutions/3353011

Hi all, Anyone tried using Templates with Managed Block Storage? I created a VM on MBS and then took a snapshot. This worked but as soon as I created a Template from snapshot, the template got created but there is no disk attached to the template. Anyone seeing something similar? Thanks

Managed Block Storage issues
by Shantur Rathore 28 Sep '21

28 Sep '21

Hi all, I am trying to set up Managed block storage and have the following issues. My setup: Latest oVirt Node NG : 4.4.8 Latest oVirt Engine : 4.4.8 1. Unable to copy to iSCSI based block storage I created a MBS with Synology UC3200 as a backend ( supported by Cinderlib ). It was created fine but when I try to copy disks to it, it fails. Upon looking at the logs from SPM, I found "qemu-img" failed with an error that it cannot open "/dev/mapper/xxxxxxxxxx" : Permission Error. Had a look through the code and digging out more, I saw that a. Sometimes /dev/mapper/xxxx symlink isn't created ( log attached ) b. The ownership to /dev/mapper/xxxxxx and /dev/dm-xx for the new device always stays at root:root I added a udev rule ACTION=="add|change", ENV{DM_UUID}=="mpath-*", GROUP="qemu", OWNER="vdsm", MODE="0660" and the disk copied correctly when /dev/mapper/xxxxx got created. 2. Copy progress finishes in UI very early than the actual qemu-img process. The UI shows the Copy process is completed successfully but it's actually still copying the image. This happens both for ceph and iscsi based mbs. Is there any known workaround to get iSCSI MBS working? Kind regards, Shantur

Re: [ovirt-announce] Re: oVirt 4.4.8 Async update #4

Hi Diggy, If you have updated to oVirt 4.4.8 prior to 4.4.8.6 async release, it means your system got impacted. To fix it, you need to set some value to HEVM timezone and then try again (at least how I understand it). Regards, Marina.

about the Live Storage Migration
by Tommy Sway 27 Sep '21

27 Sep '21

From the document: Overview of Live Storage Migration Virtual disks can be migrated from one storage domain to another while the virtual machine to which they are attached is running. This is referred to as live storage migration. When a disk attached to a running virtual machine is migrated, a snapshot of that disk's image chain is created in the source storage domain, and the entire image chain is replicated in the destination storage domain. As such, ensure that you have sufficient storage space in both the source storage domain and the destination storage domain to host both the disk image chain and the snapshot. A new snapshot is created on each live storage migration attempt, even when the migration fails. Consider the following when using live storage migration: You can live migrate multiple disks at one time. Multiple disks for the same virtual machine can reside across more than one storage domain, but the image chain for each disk must reside on a single storage domain. You can live migrate disks between any two storage domains in the same data center. You cannot live migrate direct LUN hard disk images or disks marked as shareable. But where do users perform online storage migrations? There seems to be no interface.

Re: About the vm memory limit
by Tommy Sway 27 Sep '21

27 Sep '21

In fact, I am very interested in the part you mentioned, because my environment is running relational database, which usually requires a large amount of memory, and some systems clearly need to configure HUGEPAGE memory (such as Oracle). Could you elaborate on some technical details about the management of huge page memory? And the difference between 4.3 and 4.4 in this respect? Thank you very much!

If you have 256G per CPU, it's best to stay into that range. Also, consider disabling transparent huge pages on the host & VM.

For some virtual machines, 4G memory is enough, while for some virtual machines, 64GB memory is needed.

Hypervisor broken
by Hans Scheffers 27 Sep '21

27 Sep '21

Hi all, I am new here, been searching the mailing list on a regular base when I encountered problems and till now I always was able to keep the system up & running. As said... till now... I have oVirt at home, and I have about 7 vm's running on it. Lately I have had some troubles with my electricity, which results in a complete power outage on a irregular base. Yesterday I had a power outage which left the system unbootable with the following errors: error: ../../grub-core/loader/i386/pc/linux.c:170:invalid magic number. error: ../../grub-core/loader/i386/pc/linux.c:1418:you need to load the kernel first. Press any key to continue Normally this can be solved following https://access.redhat.com/solutions/5829141, but his time also the files in /boot had a size of 0 bytes. So basically i did not have a working kernel on the system anymore. https://www.thegeekdiary.com/centos-rhel-7-how-to-install-kernel-from-res... does work for CentOS 8 also, but the ovirt 4.8 iso does not have the same directory structure. Using CentOS 8 installs a kernel, but not a bootable system. When booting the ovirt kernel, I get a rescue prompt with the following error: "Warning: /dev/onn/ovirt-node-ng-4.4.6.3-0.20210518.0+1 does not exist" Is there a way i can start the installer in troubleshooting mode so I can do a reinstall and keep the current configuration or can I just reinstall and import the current datacenter in it?

Hosted Engine cluster version compatib.
by Andrea Chierici 24 Sep '21

24 Sep '21

Dear all, I have just updated my ovirt installation, with self hosted engine, from 4.4.5 to 4.4.8.5-1. Everything went smoothly and in a few minutes the system was back up and running. A little issue is still puzzling me. I am asked to update from 4.5 to 4.6 the cluster and data center compatibility level. When I try to issue the command from the cluster config I get this error: > Error while executing action: Cannot update cluster because the update > triggered update of the VMs/Templates and it failed for the following: > HostedEngine. To fix the issue, please go to each of them, edit, > change the Custom Compatibility Version (or other fields changed > previously in the cluster dialog) and press OK. If the save does not > pass, fix the dialog validation. After successful cluster update, you > can revert your Custom Compatibility Version change (or other > changes). If the problem still persists, you may refer to the > engine.log file for further details. It's very strange because the config of the hostedengine is "plain" and there are no constrains on compatibility version, as you can see in this picture: In any case, if I try to force compatibility with 4.6 I get this error: > Error while executing action: > > HostedEngine: > > There was an attempt to change Hosted Engine VM values that are > locked. So I am stuck. Not a big deal at the moment, but sooner or later I will have to do this upgrade and I don't know where I am wrong. Can anybody give a clue?

Hi, In the second engine dep run in Hyperconverged deployment I get red "Ooops!" in cockpit. I think it fails on some networking setup. The first oVirt Node says "Hosted Engine is up!" but the other nodes is not added to HostedEngine yet. There is no network connectivity to the Engine outside node1, I can ssh to engine from node1 on the right IP-address. Please tell what logs I should pull.
