Upgrading oVirt Manager

Sat, 26 Dec 2020 20:48:29 +1100

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

Configure oVirt Manager to Authenticate Against FreeIPA

Sat, 26 Dec 2020 00:08:02 +1100

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.

Passed Red Hat Virtualization Exam EX318

Wed, 09 Dec 2020 14:32:35 +1100

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 4.3.
