Hi Gianluca,

As mentioned in below RFE, EL 8.4 is not enough, you also need Advanced Virtualization 8.4 (libvirt >= 7.0.0) and AFAIK this has not been released upstream:


So right now you can use 4.6 cluster level only on hosts running on CentOS Stream.

Also the error message tells you that all your Up hosts need to provide EL + AV 8.4 features before you upgrade cluster level. But of course you can upgrade them one by one, it's not required to put all hosts into Maintenance before upgrade.

OK, thanks for the note.
Inside Doc Text of the bugzilla above there is:
"
New features available in compatibility 4.6 are tracked as separate bugs depending on this bug.
"
Have you the id of the bugs related to these new features provided in 4.4.6?

BTW [OT]: is RHV-H 4.4.6 host image ready for cluster level 4.6 or not yet?
