| Description: | Kernel-based Virtual Machine (KVM) offers a full virtualization solution for Linux on numerous hardware platforms. The virt:rhel module contains packages which provide user-space components used to run virtual machines using KVM. The packages also provide APIs for managing and interacting with the virtualized systems.
The following packages have been upgraded to a later upstream version: qemu-kvm (6.2.0), libvirt (8.0.0), libvirt-python (8.0.0), perl-Sys-Virt (8.0.0), seabios (1.15.0), libtpms (0.9.1). (BZ#1997410, BZ#2012802, BZ#2012806, BZ#2012813, BZ#2018392, BZ#2027716, BZ#2029355)
