OpenStack Charms 19.10 – Train, Policy Overrides and more
This release introduces support for OpenStack Train on Ubuntu 18.04 LTS (via Ubuntu Cloud Archive) and Ubuntu 19.10. Train is the 20th OpenStack release which brings a lot of interesting features on its own. One of the most important additions are telco-specific extensions to Nova live migration. The benefits of moving guest machines from one hypervisor to another without shutting down the operating system of the guest are now also available in telco-specific environments with NUMA topology, pinned CPUs, SR-IOV ports attached and huge pages configured.

For more information about OpenStack Train, please refer to the upstream release notes.
