Current Series Release Notes¶

20.0.0¶

Adds the deployment of an OCI image registry with the eventual goal for artifacts to be hosted by the image registry in the default case for Bifrost. This feature is now installed by default utilizing the bifrost-registry-install role.

Adds variables to configure authentication parameters in the bifrost-ironic-install role, where IPA images are downloaded. The new variables are ipa_download_url_username, ipa_download_url_password, ipa_download_force_basic_auth and ipa_download_unredirected_headers. Ramdisk and kernel images can be separately configured using ipa_ramdisk/ipa_kernel prefixes, e.g. ipa_ramdisk_download_url_username. See documentation of the get_url and uri Ansible modules for more details on how to use these variables.

The OCI image registry installation can now be disabled using the enable_registry variable or the --disable-registry CLI flag. The registry remains enabled by default to maintain backward compatibility.

To disable during installation:
- CLI: bifrost-cli install --disable-registry
- Ansible: -e enable_registry=false

Adds support for using Open vSwitch (OVS) as a virtual switch for testing environments. Setting test_vm_switch_type to ovs creates 3 separate VLANs for comprehensive network testing: one dedicated as an inspection network, another for the final tenant network, and a third for all other network types (cleaning, rescuing, servicing, etc.). This enhancement enables testing of the standalone networking feature with proper VLAN configuration support through the networking generic switch driver.

Added support for testing the new standalone Ironic networking service. When enable_ironic_networking is set to True, the standalone networking service is launched alongside the main Ironic service using the ironic-networking networking driver. Generated inventory files now include port and driver information to utilize this new functionality. This feature enables testing of advanced network configuration capabilities in standalone Ironic deployments.

When testing standalone Ironic networking functionality, if test_vm_use_static_local_link_connection_info is set to false, then manual inspection must be performed on nodes prior to deployment to ensure local_link_connection information is available for switch port identification. Without this information, nodes may be silently provisioned on incorrect VLANs.

The default IPA ramdisk used in bifrost is now debian DIB based which is smaller and compatible with more versions of GRUB.

Using tinyipa as ironic-python-agent ramdisk is not supported anymore. Bifrost has switched to using DIB (diskimage-builder) based IPA ramdisks for all CI jobs. All Bifrost CI jobs now use dibipa (DIB-based IPA) in their names to clearly indicate they use full-featured IPA ramdisks built with diskimage-builder. Test VM memory has been increased from 1024 MB to 4096 MB to accommodate the larger DIB-based IPA ramdisks (~500 MB vs ~80 MB for tinyipa). Three legacy job names with tinyipa in their names are kept for backward compatibility with other OpenStack projects (Ironic, openstacksdk, ansible-collections-openstack). These jobs now use DIB-based IPA despite their names. Projects using these legacy job names should migrate to the new dibipa job names when ready.

Fixes the dnsmasq DHCP provider on the Debian family of operating systems by providing the correct dnsmasq leases file path.

The ILO driver has been removed as of the 2026.1 release. The ‘ilo’ and ‘ilo5’ hardware types have been removed from the default ‘enabled_hardware_types’ list and all related configuration options, dependencies, and interface support have been removed.

Previously, an /etc/ironic/htpasswd file was only generated when Keystone was not used as an authentication source. This artifact is now always generated for OCI image registry support.
