New features¶
PCI passthrough support in OpenStack¶
Added support for the Peripheral Component Interconnect (PCI) passthrough feature in OpenStack to use, mainly, as a part of the SR-IOV network traffic acceleration technique. Now, MOS enables the user to configure Nova on a per-node basis to allow PCI devices to be passed through from hosts to virtual machines.
OpenStack Victoria support¶
TechPreview
Implemented support for OpenStack Victoria with Neutron OVS and Tungsten Fabric 5.1.
SR-IOV for OpenStack¶

Hyper-converged OpenStack compute nodes¶
TechPreview
Implemented the capability to colocate components on the same host, for example, Ceph OSD and OpenStack compute.
Tungsten Fabric monitoring¶
Enhanced StackLight to monitor Tungsten Fabric and its components, including Casandra, Kafka, Redis, and ZooKeeper. Implemented the Tungsten Fabric alerts and Grafana dashboards. The feature is disabled by default. You can enable it manually during or after the Tungsten Fabric deployment.
Alert inhibition rules¶
Implemented alert inhibition rules to provide a clearer view on the cloud status and simplify troubleshooting. Using alert inhibition rules, Alertmanager decreases alert noise by suppressing dependent alerts notifications. The feature is enabled by default. For details, see Operations Guide: Alert dependencies.
Integration between Grafana and Kibana¶
Implemented integration between Grafana and Kibana by adding a View logs in Kibana link to most Grafana dashboards, which allows you to immediately view contextually relevant logs through the Kibana web UI.

Added the capability to configure the Transport Layer Security (TLS) protocol
for a Ceph RGW public endpoint using MOS TLS if enabled,
or using a custom ingress specified in the KaaSCephCluster custom
resource.
