oVirt 2.5.1.2 HCI Gluster Recovery Options
by Clint Boggio 12 Dec '22

12 Dec '22

Greetings oVirt community; I've got a three-node HCI cluster with hosted engine and on one of the three nodes I lost the underlying RAID array under the Gluster bricks. It looks like I'm going to have to rebuild the RAID array and thus likely lose the Gluster configuration that lives there. The host OS (oVirt Node) is fine and it's just the Gluster/RAID piece that is affected. Can one of you please point me to the best documentation link to the process of re-configuring that failed node to be identical to the rest of the nodes please ? It's configured for replica-three and I don't want to have a problem with nodes 2 and 3 before I get node 1 back up and healthy. Any help will be greatly appreciated.

Detach Button Greyed Out After Putting Storage Domain Into Maintenance
by mark.matlock＠oneildata.com 12 Dec '22

12 Dec '22

Trying to safely remove some storage domains in oVirt and am not getting errors or log messages explaining why the <Detach> button is greyed out. It succeeds in deactivating but I can't safely remove it. The only button available is <Activate> Also, I've noticed unless I checkmark 'Ignore OVF Update Failures', the storage domain will exit Maintenance and go right back to Active status. Software Version: 4.3.10.4-1.el7 Logged in as admin

Host kernel command line incorrectly quoted in oVirt 4.5.3.2
by Gianluca Amato 12 Dec '22

12 Dec '22

Hi all. I recently changed the kernel command line of one of my hosts using oVirt Manager (I use a custom kernel command line, not one obtained by selecting the standard features). This did not work as expected. The entire kernel command line was saved in /boot/loader/entries surrounded by single quotes, making it useless for the kernel. I may later fix the problem by connecting to the host and removing the single quotes by the files in /boot/loader/entries. I am sure the same procedure used to work in previous versions of oVirt. Has someone else encountered this problem ? I would be glad to submit a bug on bugzilla, but submitting bugs for oVirt seems to be blocked.

Combining vNUMA and dedicated CPU Pinning Policy
by Gianluca Amato 12 Dec '22

12 Dec '22

Hello, as stated in the subject, I am trying to combine the "dedicated" CPU Pinning Policy with vNUMA. My host has 2 sockets, 28 cores per socket and 2 threads per core. In each socket I allocated 128 hugepages of 1GB each. This is the output of "numactl --hardware": ------------ available: 2 nodes (0-1) node 0 cpus: 0 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 42 44 46 48 50 52 54 56 58 60 62 64 66 68 70 72 74 76 78 80 82 84 86 88 90 92 94 96 98 100 102 104 106 108 110 node 0 size: 257333 MB node 0 free: 122518 MB node 1 cpus: 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 39 41 43 45 47 49 51 53 55 57 59 61 63 65 67 69 71 73 75 77 79 81 83 85 87 89 91 93 95 97 99 101 103 105 107 109 111 node 1 size: 257993 MB node 1 free: 124972 MB node distances: node 0 1 0: 10 21 1: 21 10 ----------- I would like to dedicate one half of all the cores to a single guest. I created a VM with 2 sockets, 14 cores per socket and 2 threads per core, using the "dedicated" CPU Pinning Policy. If a set "NUMA Node Count" to zero, the VM starts and works flawlessy. However, all virtual cores are allocated in the first physical socket. If I set "NUMA Node Count" to 2 (without pinning vNUMA nodes to host NUMA nodes) I cannot start the VM since I get the error message: "The host xyz did not satisfy internal filter CpuPinning because it doesn't have enough CPUs for the dedicated CPU policy that the VM is set with.. ". Same thing happens if I set "NUMA Node Count" to 1. Am I doing something wrong ?

Re: Recombining disks under a single VM

Scratch this query. It appears we had two identical images. It wouldn't permit importing due to matching disk id's. From: Matthew.Stier(a)fujitsu.com <Matthew.Stier(a)fujitsu.com> Sent: Saturday, December 10, 2022 10:24 PM To: users(a)ovirt.org Subject: [ovirt-users] Recombining disks under a single VM Up until now, we've been using iSCSI as the storage on all of our datacenters, and when we need to bulk move VMs, we moved iSCSI storage domains. We've just setup our first datacenter with Fiber Channel storage, and no connectivity to our iSCSI storage. For this move we have fallen back to using NFS storage domains, to move the necessary VMs from datacenter ONE to datacenter TWO. The bulk of the transfer went fine, but for about one dozen two disk VMs both disks did not get moved at the same time. So now I have one dozen VMs with only one drive on datacenter TWO and the other drive as an un-importable VM on the NFS storage partition, mounted on datacenter TWO. Any hints on how I "merge" these two, back into one function VM? == Matthew.Stier(a)fujitsu.com<mailto:Matthew.Stier@fujitsu.com>

Migrating to keycloak
by eric.j.gillingham＠jpl.nasa.gov 08 Dec '22

08 Dec '22

I have an existing ovirt cluster, and I'm trying to migrate it from the internal sso and LDAP over to keycloak but am kind of at a loss. I followed the Activation procedures on https://github.com/oVirt/ovirt-engine-keycloak/blob/master/keycloak_usage.m… and am able to login to the keycloak console fine, but when I try to access the ovirt-engine admin panel I just get an internal server error. httpd log contains "oidc_util_json_string_print: oidc_util_check_json_error: response contained an "error" entry with value: ""Realm does not exist""" Does engine-setup not configure the keycloak it creates with the proper configuration for ovirt? The apache config seems to have some password and other settings for oidc, so that end got configured, but not the keycloak side. There's no ovirt-engine or other ovirt related clients inside the newly created keycloak.

centos-stream-release-8.6-1.el8.noarch vs redhat-release-8.7-0.3.el8.x86_64
by eshwayri＠gmail.com 07 Dec '22

What is the best way to resolve the below error. All other EL8 packages are now at 8.7. (--nobest) but the release file(s) aren't updating because this package won't upgrade. The blocking centos-stream-release-8.6-1.el8.noarch package is a pre-req for all the oVirt files, so I can't remove it. I suspect all oVirt is using from it are the repos. Do I force install redhat-release-8.7-0.3.el8.x86_64? Is there a way to do that? [root@kvmo-el8 /]# yum update Updating Subscription Management repositories. Last metadata expiration check: 2:28:57 ago on Wed 07 Dec 2022 03:25:45 PM EST. Error: Problem: installed package centos-stream-release-8.6-1.el8.noarch obsoletes redhat-release < 9 provided by redhat-release-8.7-0.3.el8.x86_64 - cannot install the best update candidate for package redhat-release-8.6-0.1.el8.x86_64 - problem with installed package centos-stream-release-8.6-1.el8.noarch (try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
