The OpenStack community today released Train, the 20th version of the most widely deployed open source cloud infrastructure software.
Among the many enhancements provided in Train, three highlights are:
Several Cinder drivers add support for new features like multi-attach and consistency groups.
Nova offers live migration support for servers with a NUMA topology, pinned CPUs and/or huge pages, when using the libvirt compute driver. Nova also delivers live migration support for servers with SR-IOV ports attached when using the libvirt compute driver. This enhancement, driven by the StarlingX project, enables a hypervisor to run both pinned and unpinned workloads in the same hypervisor.
Improved documentation was a community-wide goal for the Train cycle in an effort to be a more accessible open source community. OpenStack operators can now access PDF-generated documentation by project.
