This upgrade applies to the self-hosted engine of oVirt Manager. We need to first put the oVirt environment to the global maintenance mode. [root@trex ~]# hosted-engine --set-maintenance --mode=global To check the availability of oVirt Manager, run engine-upgrade-check command on the oVirt Manager machine. [root@ovirtm ~]# engine-upgrade-check ...omitted...

This is quick note on how to configure an oVirt Manager or RHV Manager to use the FreeIPA to provide user external authentication. Here’s my servers’ information: IPA server: ipa.angkorian.io (CentOS 8.3.2011) oVirt Hosted-Engine: ovirtm.angkorian.io (CentOS 8.3.2011) IPA user: ovirtadmin First, open SSH connection to ovirtm as root and ensure that ovirt-engine-extension-aaa-ldap-setup package is installed. Here is a tip to figure out the name of this package - I’d search for ovirt*ldap....

We can create a fullback of oVirt engine without stopping the oVirt infrastructure using the ovirt-backup command. To do this, ssh to the oVirt hosted-engine and specify this backup scope, the name of backup file and the name of the log file. [root@ovirtm ~]# engine-backup --scope=all --mode=backup --file=ovirtm-backup_20201223.tgz --log=backup_20201223.log Start of engine-backup with mode 'backup' scope: all archive file: ovirtm-backup_20201223.tgz log file: backup_20201223.log Backing up: Notifying engine - Files - Engine database 'engine' - DWH database 'ovirt_engine_history' Packing into file 'ovirtm-backup_20201223....

This note is, again, for me to remind myself in case I couldn’t recall how to do this in the future. To remove a storage domain from the cluster, use the following steps: Click Storage -> Domains Click on the name of the storage domain to open the details view Click on the Data Center tab Click on Maintenance button, then click on OK The Detach button becomes active, click on it....

Another month, another Red Hat exam has been ticked off the list. This time, it’s about the Red Hat Virtualization, a technology based on oVirt. The code name of the exam is EX318, and as rumours has it, it’s one of the easiest Red Hat exams; I can’t agree more. The exam’s duration is 3 hours; it’s a hand-on closed book exams. The exam is based on Red Hat Virtualization version 4....
