Add opt-in SPICE support for Rocky via COPR.

2026-06-29T00:55:46+00:00

RHEL9 dropped SPICE support from qemu-kvm, and Rocky Linux followed suit. Up until now the documented guidance has been to use the Debian or Ubuntu container images if you want to serve the ``spice-direct`` console type, because the stock Rocky nova-libvirt image will simply fail to start any SPICE-enabled instance. This change adds a second version of the nova-libvirt container image called nova-libvirt-spice. It is always built, but is identical for all supported container base distributions except for Rocky Linux. In the Rocky Linux case, this container adds the community maintained ligenix/enterprise-qemu-spice COPR repository that provides a rebuild of ``qemu-kvm`` with SPICE support re-enabled for both EPEL 9 and EPEL 10. Which nova-libvirt container should be used in a given deployment is delegated to logic in kolla-ansible, based on the deployer's settings in globals.yml. The COPR is a third-party rebuild with no vendor support contract. The release note and support matrix are updated to describe the opt-in path and call this caveat out explicitly. The earlier "you must use Debian or Ubuntu" wording in the support matrix is softened here, rather than by retroactively editing the kerbside container-build patch that introduced it, so that this feature can land (or not land) independently of the earlier change. Partial-Bug: #2131793 (spice-direct consoles) Prompt: I am interested in seeing how we would go about using https://copr.fedorainfracloud.org/coprs/ligenix/enterprise-qemu-spice/ to add SPICE support back to the Kolla build Rocky Linux containers as a new patch in the kolla/ORDER list. Could you please investigate options here?

Implement container image build for kerbside.

2026-06-03T03:10:47+00:00

This change adds images for Kerbside. Kerbside is a SPICE protocol native proxy used to expose the new spice-direct console type provided by Openstack Compute. This allows high fidelity virtual desktop experiences without requiring transcoding of the console into HTML5 in Horizon, or allowing users direct access to the console ports on your hypervisors. Sadly, Red Hat chose to remove SPICE support from qemu in RHEL9, and Rocky Linux has followed along. You therefore _must_ run the Debian or Ubuntu container images if you wish to use the ``spice-direct`` console type. Architecturally Kerbside has two components -- an API service which turns console access URLs from Nova into URLs to ``.vv`` files, and a proxy service which actually proxies the SPICE traffic. These are handled as separate container images here because they're quite different. One is a WSGI REST API, and the other is a daemon. It is also likely that deployers would choose to host these on different machines. Finally, the proxy service needs to be special cased in load balancing because it strongly expects to terminate TLS itself. The haproxy is therefore configured as a layer 4 proxy in this case.
