Michal, Many thanks for the sharing! That sounds a good way to my situation, i actually want to upgrade the libvirt on several RHEL 8 compute nodes of an OpenStack deployment. I setup CentOS env for verification before the actual upgrade. But following your instruction, i have two questions here, would you kindly share more details with the processes? 1) Assume i want to upgrade to version 6.1.0, which one of the src.rpms should i use? all the three have same effects for installing the dependent packages?

Yes, you are right! I made mistake for the version number. Below check is from my newly installed CentOS 8 env, you can see when i choose the "Server with GUI" environment groups, the libvirt was bundle installed.
