oVirt 4.4.6 Fourth Release Candidate is now available for testing

The oVirt Project is pleased to announce the availability of oVirt 4.4.6 Fourth Release Candidate for testing, as of April 15th, 2021.

This update is the sixth in a series of stabilization updates to the 4.4 series.

Rebase on CentOS Stream

Starting with oVirt 4.4.6 RC4 both oVirt Node and oVirt Engine Appliance are based on CentOS Stream.

You can still install oVirt 4.4.6 on Red Hat Enterprise Linux,  CentOS Linux or equivalent.

Please note that when 4.4.6 will be released as generally available, existing oVirt Nodes updating to 4.4.6 will automatically be based on CentOS Stream.

Help testing this release candidate will help ensuring a smooth experience for your main installation.

How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1

Note: Upgrading from 4.4.2 GA or later should not require re-doing these steps, if already performed while upgrading from 4.4.1 to 4.4.2 GA. These are only required to be done once.

Due to Bug 1837864 - Host enter emergency mode after upgrading to latest build 

If you have your root file system on a multipath device on your hosts you should be aware that after upgrading from 4.4.1 to 4.4.6 you may get your host entering emergency mode.

In order to prevent this be sure to upgrade oVirt Engine first, then on your hosts:

1. Remove the current lvm filter while still on 4.4.1, or in emergency mode (if rebooted).

2. Reboot.

3. Upgrade to 4.4.6 (redeploy in case of already being on 4.4.6).

4. Run vdsm-tool config-lvm-filter to confirm there is a new filter in place.

5. Only if not using oVirt Node:
   - run "dracut --force --add multipath” to rebuild initramfs with the correct filter configuration

6. Reboot.
