I was looking at those studies but not sure how old they are. What I can see is that our oVirt deployment seems bigger than any of those studies but I can be wrong. ------ Original Message ------ Received: 01:08 AM MDT, 09/02/2022 From: Sandro Bonazzola <sbonazzo(a)redhat.com> To: jlhm(a)usa.net Cc: oVirt Users <users(a)ovirt.org> Subject: Re: [ovirt-users] How many oVirt cluster, hosts and VMs do you have running? > Would something like an oVirt counter help? > https://github.com/oVirt/ovirt-site/pull/3056 > > > Il giorno ven 2 set 2022 alle ore 08:26 ha scritto: > > > Hi, just trying to understand how our oVirt deployment compare to others. > > - 75 cluster (and 75 Data centers as we map them 1 to 1 due to security > > requirements) spanning +3 data centers > > - 328 oVirt servers > > - +1900 VMs running > > > > Majority are still on 4.3 (CentOS 7) but our engines (4 of them) runs > > RedHat 8/oVirt 4.4.

How many oVirt cluster, hosts and VMs do you have running?
by jlhm＠usa.net 02 Sep '22

02 Sep '22

Hi, just trying to understand how our oVirt deployment compare to others. - 75 cluster (and 75 Data centers as we map them 1 to 1 due to security requirements) spanning +3 data centers - 328 oVirt servers - +1900 VMs running Majority are still on 4.3 (CentOS 7) but our engines (4 of them) runs RedHat 8/oVirt 4.4. Working to upgrade all hypervisors to RedHat 8 (or Rocky 8)/oVirt 4.4. When that is done we will start to upgrade to latest oVirt version but it takes time due to the size of our environment and we move slowly to ensure stability.

Ubuntu NFS
by thilburn＠generalpacific.com 01 Sep '22

01 Sep '22

Hello, I was having trouble with getting an Ubuntu 22.04 NFS share working and after searching for hours I was able to figure out what was needed. Below is what I found if anyone else runs into this. My error was engine.log "...Unexpected return value: Status [code=701, message=Could not initialize cluster lock: ()]" Host supervdsm.log -open error -13 EACCES: no permission to open /ThePath/ids -check that daemon user sanlock *** group sanlock *** has access to disk or file. The fix was changing /etc/nfs.conf manage-gids=y ( Which is the default ) to # manage-gids=y ( Commenting this sets the default which is no ) It looks like in the past the fix was to change /etc/default/nfs-kernel-server Line RPCMOUNTDOPTS="--manage-gids" which I didn't need to change.

how kill backup operation
by Diego Ercolani 01 Sep '22

01 Sep '22

Hello I saw there are other thread asking how to delete disk snapshots from backup operation. We definitively need a tool to kill pending backup operations and locked snapshots. I Think this is very frustrating ovirt is a good piece of software but it's very immature in a dirty asyncronous world. We need a unified toolbox to clean manually and do database housekeeping.

Interested in contributing with Spanish translation.
by Luis Pereida 01 Sep '22

01 Sep '22

Hello, My name is Luis Pereida, I am Mexican, from Guadalajara and I am currently an application security specialist. Some time ago I met the O-Virt project and it helped me a lot to solve many situations where virtualization was the perfect option. Since some time ago I have been thinking about how to contribute to the project, and talking with some friends, they would like to have documentation in Spanish. Although English is basic for us, many times the context or expressions are hard to understand. I would like to help with that. How can I do it? I see that it is necessary to use a Zanata account. How can I get an account? Regards and thanks for being so supportive of the community.

by Andrei Verovski 31 Aug '22

31 Aug '22

Hi, I have engine version 4.4.10.7-1.el8, is it possible to set up new node host on CentOS Stream 9, or I need to upgrade engine to version 4.5 first (which is not right now possible because of some quite old nodes) ? Thanks Andrei

Moving SelfHosted Engine
by murat.celebi＠dbpro.com.tr 31 Aug '22

31 Aug '22

Hello We have got an Production ovirt installation with 1 datacenter and 2 clusters. Default Cluster has got 2 hosts in it. kvm01 and kvm02. PrimarySite cluster has got 2 hosts in it. kvm03 and kvm04 Our Self hosted engine is running on kvm01. We need to migrate the Selfhosted-engine to kvm03 or kvm04 since the hosts kvm01 and kvm02 hosts are going to be retired. Anyone has any idea how this can be accomplished?

Failed to delete snapshot (again)
by Giulio Casella 30 Aug '22

30 Aug '22

Hi folks, since some month I have an issue with snapshot removals (I have storware vprotect backup system, heavily using snapshots). After some time spent on a bugzilla (https://bugzilla.redhat.com/show_bug.cgi?id=1948599) we discovered that my issue is not depending on that bug :-( So they pointed me here again. Briefly: sometime snapshot removal fails, leaving snapshot in illegal state. Trying to remove again (via ovirt UI) keeps failing and doesn't solve. The only way to rebuild a consistent situation is live migrating affected disk to another storage domain; after moving the disk, snapshot is no more marked illegal and then I can remove it. You can imagine this is a bit tricky, specially for large disks. In my logs I can find: 2022-08-29 09:17:11,890+02 ERROR [org.ovirt.engine.core.bll.MergeStatusCommand] (EE-ManagedExecutorService-commandCoordinator-Thread-1) [0eced56f-689d-422b-b15c-20b824377b08] Failed to live merge. Top volume f8f84b1c-53ab-4c99-a01d-743ed3d7859b is still in qemu chain [0ea89fbc-d39a-48ff-aa2b-0381d79d7714, 55bb387f-01a6-41b6-b585-4bcaf2ea5e32, f8f84b1c-53ab-4c99-a01d-743ed3d7859b] My setup is ovirt-engine-4.5.2.4-1.el8.noarch, with hypervisors based on oVirt Node 4.5.2 (vdsm-4.50.2.2-1.el8). Thank you in advance. Regards, gc

Ovirt 4.4.7, can't renew certificate of ovirt engine (certificates expired)
by vk＠itiviti.com 30 Aug '22

30 Aug '22

Hi Team, I'm looking for your help since I didn't find any clear documentation. Is there somewhere in ovirt website a clear documentation about how to renew the engine certificates located in /etc/pki/ovirt-engine/certs/ We have an engine GUI not working, showing error message "PKIX path validation failed: java.security.cert.CertPathValidatorException: validity check failed". After checking, all the cert in /etc/pki/ovirt-engine/certs/ are expired. I didn't find a clear documentation on ovirt website, or even on redhat website (it was always about host but not the engine) Anyway I've read that the renew process can be done via "engine-setup --offline", but when I try it, it generates this error: --== PKI CONFIGURATION ==-- [ ERROR ] Failed to execute stage 'Environment customization': Unable to load certificate. See https://cryptography.io/en/latest/faq/#why-can-t-i-import-my-pem-file for more details. and in log file: File "/usr/lib64/python3.6/site-packages/cryptography/hazmat/backends/openssl/backend.py", line 1371, in load_pem_x509_certificate "Unable to load certificate. See https://cryptography.io/en/la" ValueError: Unable to load certificate. See https://cryptography.io/en/latest/faq/#why-can-t-i-import-my-pem-file for more details. 2022-08-29 19:16:29,502+0200 ERROR otopi.context context._executeMethod:154 Failed to execute stage 'Environment customization': Unable to load certificate. See https://cryptography.io/en/latest/faq/#why-can-t-i-import-my-pem-file for more details. I've also tried the manual procedure (using /usr/share/ovirt-engine/bin/pki-enroll-pkcs12.sh) mentioned in https://users.ovirt.narkive.com/4ugjgicE/ovirt-regenerating-new-ssl-certifi… (message from Alon Bar-Lev), but the 4th command always says I enter a wrogn apssword, but it's not. we are blocked here and we can't use our ovirt cluster, so it's pretty blocking. Thx a lot in advance
