[ovirt-users] Re: Requirements to put to cluster version 4.6

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: https://bugzilla.redhat.com/show_bug.cgi?id=1933974 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. Regards, Martin
