oVirt 4.4.5 Eighth Release Candidate is now available for testing


The oVirt Project is pleased to announce the availability of oVirt 4.4.5 Eighth Release Candidate for testing, as of March 4th, 2021.


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

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 4.4.5 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 4.4.5 (redeploy in case of already being on 4.4.5).

  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.
