Hi Sandro,
thanks for the release!

Should this fix the upgrade problems to cluster version 4.5 too when using CentOS 8.3 + updates?

Yes
 


Hi Sandro,
I confirm that on a test cluster with 3 plain CentOS 8.3 hosts and an external CentOS 8.3 based engine I was able to update all of them to 4.4.4 and then update both cluster and DC level to 4.5.
Can you recall, apart from being now at the latest level, what kind of new features I should expect in 4.5 vs 4.4 so that I can also test and use them for improvements (eg in storage domain version/features, incremental backup, snapshotting features, export and such...)?

Cluster compatibility level has been introduced with:
Bug 1877675 - [RFE] Introduce Datacenter and cluster level 4.5

It tracks:
- Bug 1725166 - [RFE] Private VLAN / port isolation
- Support for Intel Icelake Server Family 
- Bug 1814565 - Report disk.usage for VMs with RHEL 8 guests
- Bug 1852718 - vGPU: VM failed to run with mdev_type instance
- Bug 1853194 - VM with disk on iscsi on environment with SELinux enforced fails to start on host - Exit message: Wake up from hibernation failed:internal error: child reported (status=125): unable to set security context
- Bug 1876605 - VM with scsi hostdev (scsi_generic custom property) fails on start:'node-name too long for qemu'

+Martin Perina , +Arik Hadas , +Tal Nisan , +Dominik Holler  feel free to add if I missed something.
I think that having a page on oVirt documentation with features and requirements per supported cluster compatibility level would help.
Gianluca, maybe you can open a bug for it?


 

thanks
Gianluca
