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?

[ ] libvirt-6.1.0-0rc1.fc30.src.rpm 26-Feb-2020 13:04 7.9M  
[ ] libvirt-6.1.0-0rc2.fc30.src.rpm 29-Feb-2020 09:26 7.9M  
[ ] libvirt-6.1.0-1.fc30.src.rpm 03-Mar-2020 14:11 7.9M  
[ ] libvirt-6.1.0-rc1.tar.xz 26-Feb-2020 10:52 7.9M  
[TXT] libvirt-6.1.0-rc1.tar.xz.asc 26-Feb-2020 13:04 488  
[ ] libvirt-6.1.0-rc2.tar.xz 29-Feb-2020 09:25 7.9M  
[TXT] libvirt-6.1.0-rc2.tar.xz.asc 29-Feb-2020 09:26 488  
[ ] libvirt-6.1.0.tar.xz 03-Mar-2020 14:11 7.9M  
[TXT] libvirt-6.1.0.tar.xz.asc


2) if then i download the libvirt-6.1.0.tar.xz for making the rpm, do i need to write  a spec file on my own for the rpmbuild tool to work?


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.

Hello Experts,


Is it possible to perform an in-place upgrade for libvirt.

Assume, i have a CentOS 8 installation (choose server with GUI) with
libvirt version 4.5.1 and i want to upgrade the libvirt to version
6.0.0, how to implement a perfect replacement for all the related files
(libraries, header files, etc)?

Does anybody here has the experience for this?

The way I usually go about this is:

1) download the .src.rpm for the libvirt package
2) yum-builddep libvirt.src.rpm

This installs all the build deps of libvirt. Then just download the
libvirt.tar.xz you want (or checkout the tag in the repo) and 'make
rpm'. Note, this will not contain RHEL-only patches. That is more
advanced topic.


BTW: I don't think I've seen 4.5.1 in CentOS, where did you get it from?
