You can give it a run from https://buildlogs.centos.org/c7.1908.00.x86_64/libvirt/20190809003358/4.5.0-23.el7.x86_64/ If it's not working there, you'll need to file a bug on RHEL for being considered for backport or stick to CentOS Virtualization SIG version you are already consuming from libivrt-latest repository. > Thanks a lot, > > Oleksandr > > _______________________________________________ > CentOS-virt mailing list > CentOS-virt at centos.org > https://lists.centos.org/mailman/listinfo/centos-virt > -- Sandro Bonazzola MANAGER, SOFTWARE ENGINEERING, EMEA R&D RHV Red Hat EMEA <https://www.redhat.com/> sbonazzo at redhat.com <https://www.redhat.com/>*Red Hat respects your work life balance.
