Red Hat +removed SPICE support from qemu in RHEL9 onwards, and Rocky Linux has +followed suit, so the stock Rocky Linux container images do not support +``spice-direct`` out of the box. + +As a solution, Kolla builds two copies of the ``nova-libvirt`` container +regardless of container distribution.
