Same issue happens when I deploy on single node. And I can’t find where I can edit text to replace glusterd_brick_t with system_u:object_r:glusterd_brick_t:s0 Any suggestion? Best Regards Hsutung

Live domain migration breaks Windows (UEFI) vitrual machine
by Patrick Lomakin 02 Oct '21

02 Oct '21

Greetings! I've already mentioned the problem of live disk migration between different storage domains, but yesterday I found the same problem in a new oVirt installation. My actions after deploying oVirt are: 1) Created a storage domain (iSCSI and Gluster); 2) Created a virtual machine with Windows 10 (UEFI); 3) Placed the virtual machine on the Gluster domain; 4) Started the virtual machine and started moving the disk from the Gluster storage domain to iSCSI. The disk move process was successful and error free and the virtual machine worked. However, after a reboot, the machine no longer started. The boot goes into recovery mode. All attempts to restore the machine to work were unsuccessful. I want to note that this does not happen if the machine was turned off during the disk move. In this case, it starts up without any problems. The type of domain from or to which the disk is migrated does not important. In case of live migration the Windows (UEFI) VM crashes in any case.

Upgrading from 4.3 to 4.4.8
by jasonmicron＠gmail.com 02 Oct '21

You guys scare me. Seriously. I'm trying to update from oVirt 4.3 to 4.4 using a self-hosted engine. All VMs on the host are migrated off, other than the hosted engine, from the first host I intend to update to EL 8.4, per the documentation. I installed the RPM from here: https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm I'm configuring the Engine following the upgrade document located here: https://www.ovirt.org/documentation/upgrade_guide/index.html#SHE_Upgrading_… Step 6.4, after installing the oVirt 4.4 RPM on the engine: engine-upgrade-check - I get this response: [root@labmanager yum.repos.d]# engine-upgrade-check VERB: queue package ovirt-engine-setup for update VERB: Downloading: ovirt-4.3-epel/x86_64/metalink (0%) VERB: Downloading: ovirt-4.3-epel/x86_64/metalink 10 k(100%) FAIL: Cannot queue package ovirt-engine-setup: Cannot find a valid baseurl for repo: ovirt-4.4/7 OK: Performing yum transaction rollback Error: Cannot find a valid baseurl for repo: ovirt-4.4/7 Doing a 'yum update' to just validate yum is working correctly, after installing the 44 RPM, I get this: Cannot find a valid baseurl for repo: ovirt-4.4/7 Any advice? Is the repo just not valid at the moment? Did someone forget to run a 'createrepo' after updating the YUM/DNF repo?

Reinstall without dataloss
by hans＠jiflin.nl 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

SSl vdmsd failed ssl
by Ingeniero especialista Redhat / Suse 30 Sep '21

30 Sep '21

Hello, good evening, I want to consult the following case, we have two ovirt 3.6 servers with hosted-engine, yesterday some multipath servers were presented and two machines were blocked, which was not possible to start, checking we found that the ssl of the nodes They are expired and we change them only in the nodes. We could start the hosted-engine but the two nodes are not responsive comes out in vdsm daemon vdsm [43067]: vdsm ProtocolDetector.SSLHandshakeDispatcher ERROR Error during handshake: unexpected eof I appreciate any ideas or suggestions to be able to recover normal operation. Thanks
