I'm seeing a bug with disk type showing up as preallocated in VM portal for a template disk, when it should be thin-provisioned.

All storage domains are NFS.

I setup a 4.4.5 RC engine with hosts both 4.4.5 RC and 4.4.4 on the admin portal as 'admin@internal'

I created a small CentOS 7.9 VM on NFS domain vmstore (thin provisioned storage).

I created a template from said VM, and chose 'QCOW' Disk type at that stage, default said RAW.

logout of admin portal.

login to vm portal as admin@internal

Create VM button, and create from said template created above with a name.

Continue to this part.

Note the wrong disk type displayed.  Trying to continue on fails to create VM due to 'preallocated not supported by storage domain'.

Since I never asked for 'Preallocated', I don't know why its showing up here like this.

Is there any plans to fix [1] and [2] in 4.4? After no feedback (from dec 2020) from oVirt team I decide to drop oVirt 4.4 engine, and revert to 4.3.

Current cinder integration broken broken in 4.4, but marked for deprecation only in 4.5 [3]

Thanks,

oVirt 4.4.5 Fifth Release Candidate is now available for testing

The oVirt Project is pleased to announce the availability of oVirt 4.4.5 Fifth Release Candidate for testing, as of February 11th, 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.

Important notes before you try it
