<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> </head> <body> 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? <table width="50%" cellspacing="2" cellpadding="2" border="1"> <tbody> <tr> <td valign="top"> <table style="font-family: Times; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"> <tbody> <tr> <td valign="top"><img src="https://libvirt.org/icons/unknown.gif" alt="[ ]"></td> <td><a href="https://libvirt.org/sources/libvirt-6.1.0-0rc1.fc30.src.rpm">libvirt-6.1.0-0rc1.fc30.src.rpm</a></td> <td align="right">26-Feb-2020 13:04</td> <td align="right">7.9M</td> <td> </td> </tr> <tr> <td valign="top"><img src="https://libvirt.org/icons/unknown.gif" alt="[ ]"></td> <td><a href="https://libvirt.org/sources/libvirt-6.1.0-0rc2.fc30.src.rpm">libvirt-6.1.0-0rc2.fc30.src.rpm</a></td> <td align="right">29-Feb-2020 09:26</td> <td align="right">7.9M</td> <td> </td> </tr> <tr> <td valign="top"><img src="https://libvirt.org/icons/unknown.gif" alt="[ ]"></td> <td><a href="https://libvirt.org/sources/libvirt-6.1.0-1.fc30.src.rpm">libvirt-6.1.0-1.fc30.src.rpm</a></td> <td align="right">03-Mar-2020 14:11</td> <td align="right">7.9M</td> <td> </td> </tr> <tr> <td valign="top"><img src="https://libvirt.org/icons/unknown.gif" alt="[ ]"></td> <td><a href="https://libvirt.org/sources/libvirt-6.1.0-rc1.tar.xz">libvirt-6.1.0-rc1.tar.xz</a></td> <td align="right">26-Feb-2020 10:52</td> <td align="right">7.9M</td> <td> </td> </tr> <tr> <td valign="top"><img src="https://libvirt.org/icons/text.gif" alt="[TXT]"></td> <td><a href="https://libvirt.org/sources/libvirt-6.1.0-rc1.tar.xz.asc">libvirt-6.1.0-rc1.tar.xz.asc</a></td> <td align="right">26-Feb-2020 13:04</td> <td align="right">488</td> <td> </td> </tr> <tr> <td valign="top"><img src="https://libvirt.org/icons/unknown.gif" alt="[ ]"></td> <td><a href="https://libvirt.org/sources/libvirt-6.1.0-rc2.tar.xz">libvirt-6.1.0-rc2.tar.xz</a></td> <td align="right">29-Feb-2020 09:25</td> <td align="right">7.9M</td> <td> </td> </tr> <tr> <td valign="top"><img src="https://libvirt.org/icons/text.gif" alt="[TXT]"></td> <td><a href="https://libvirt.org/sources/libvirt-6.1.0-rc2.tar.xz.asc">libvirt-6.1.0-rc2.tar.xz.asc</a></td> <td align="right">29-Feb-2020 09:26</td> <td align="right">488</td> <td> </td> </tr> <tr> <td valign="top"><img src="https://libvirt.org/icons/unknown.gif" alt="[ ]"></td> <td><a href="https://libvirt.org/sources/libvirt-6.1.0.tar.xz">libvirt-6.1.0.tar.xz</a></td> <td align="right">03-Mar-2020 14:11</td> <td align="right">7.9M</td> <td> </td> </tr> <tr> <td valign="top"><img src="https://libvirt.org/icons/text.gif" alt="[TXT]"></td> <td><a href="https://libvirt.org/sources/libvirt-6.1.0.tar.xz.asc">libvirt-6.1.0.tar.xz.asc</a></td> </tr> </tbody> </table> </td> </tr> </tbody> </table> 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. <table width="830" height="437" cellspacing="2" cellpadding="2" border="1"> <tbody> <tr> <td valign="top">[root@centos8b ~]# [root@centos8b ~]# which libvirtd /usr/sbin/libvirtd [root@centos8b ~]# libvirtd --version libvirtd (libvirt) 4.5.0 [root@centos8b ~]# [root@centos8b ~]# rpm -qa | grep libvirt libvirt-daemon-config-network-4.5.0-35.module_el8.1.0+248+298dec18.x86_64 libvirt-daemon-driver-storage-disk-4.5.0-35.module_el8.1.0+248+298dec18.x86_64 libvirt-daemon-kvm-4.5.0-35.module_el8.1.0+248+298dec18.x86_64 libvirt-daemon-driver-nwfilter-4.5.0-35.module_el8.1.0+248+298dec18.x86_64 libvirt-daemon-driver-storage-logical-4.5.0-35.module_el8.1.0+248+298dec18.x86_64 libvirt-gconfig-2.0.0-1.el8.x86_64 libvirt-daemon-4.5.0-35.module_el8.1.0+248+298dec18.x86_64 libvirt-daemon-driver-nodedev-4.5.0-35.module_el8.1.0+248+298dec18.x86_64 libvirt-gobject-2.0.0-1.el8.x86_64 libvirt-daemon-driver-storage-core-4.5.0-35.module_el8.1.0+248+298dec18.x86_64 libvirt-daemon-driver-storage-iscsi-4.5.0-35.module_el8.1.0+248+298dec18.x86_64 libvirt-daemon-driver-storage-scsi-4.5.0-35.module_el8.1.0+248+298dec18.x86_64 libvirt-libs-4.5.0-35.module_el8.1.0+248+298dec18.x86_64 libvirt-daemon-driver-interface-4.5.0-35.module_el8.1.0+248+298dec18.x86_64 libvirt-glib-2.0.0-1.el8.x86_64 libvirt-daemon-driver-storage-gluster-4.5.0-35.module_el8.1.0+248+298dec18.x86_64 libvirt-daemon-driver-storage-rbd-4.5.0-35.module_el8.1.0+248+298dec18.x86_64 libvirt-daemon-driver-secret-4.5.0-35.module_el8.1.0+248+298dec18.x86_64 libvirt-daemon-driver-storage-mpath-4.5.0-35.module_el8.1.0+248+298dec18.x86_64 libvirt-daemon-driver-network-4.5.0-35.module_el8.1.0+248+298dec18.x86_64 libvirt-daemon-driver-qemu-4.5.0-35.module_el8.1.0+248+298dec18.x86_64 libvirt-daemon-driver-storage-4.5.0-35.module_el8.1.0+248+298dec18.x86_64 [root@centos8b ~]# [root@centos8b yum.repos.d]# [root@centos8b yum.repos.d]# yum repolist CentOS-8 - PowerTools 202 kB/s | 2.0 MB 00:10 Last metadata expiration check: 0:00:01 ago on Tue 31 Mar 2020 10:37:14 PM CST. repo id repo name status AppStream CentOS-8 - AppStream 5,123 BaseOS CentOS-8 - Base 2,126 PowerTools CentOS-8 - PowerTools 1,525 extras CentOS-8 - Extras 10 [root@centos8b yum.repos.d]# yum grouplist Last metadata expiration check: 0:00:13 ago on Tue 31 Mar 2020 10:37:14 PM CST.

BTW: I don't think I've seen 4.5.1 in CentOS, where did you get it from? Michal </pre> </blockquote> </body> </html>
