In this story we collect issues we're aware of in RHEL 9.4 while starting topology support on s390x on qemu-level, ref. RHEL-10577

Goal

• As an admin I would like to use libvirt to configure and manage topology of our KVM guests in order to improve their performance.

Known shortcomings

1. Libvirt doesn't handle host configuration disparity during migrations but fails on qemu level, ref. RHEL-24843
2. The commands 'virsh nodeinfo' and 'virsh capabilities' contain
   1. erroneous information about sockets
   2. no information about books and drawers
3. The element //cpu/topology doesn't allow for drawers and books setting. Furthermore it allows for cluster, dies settings that are seemingly ignored by qemu-kvm and doesn't validate that threads must be 1 but failes when the VM starts.
4. Libvirt setvcpus don't allow for determining where in the topology a VCPU should be added.
5. Libvirt doesn't provide CPU stats for cgroupv2 (default)
