We are glad to announce the release of: nova 19.2.0: Cloud computing fabric controller This release is part of the stein stable release series. The source is available from: https://opendev.org/openstack/nova Download the package from: https://tarballs.openstack.org/nova/ Please report issues through: https://bugs.launchpad.net/nova/+bugs For more details, please see below. 19.2.0 ^^^^^^ Bug Fixes * The Compute service has never supported direct booting of an instance from an image that was created by the Block Storage service from an encrypted volume. Previously, this operation would result in an ACTIVE instance that was unusable. Beginning with this release, an attempt to boot from such an image will result in the Compute API returning a 400 (Bad Request) response. * A new config option "[neutron]http_retries" is added which defaults to 3. It controls how many times to retry a Neutron API call in response to a HTTP connection failure. An example scenario where it will help is when a deployment is using HAProxy and connections get closed after idle time. If an incoming request tries to re-use a connection that is simultaneously being torn down, a HTTP connection failure will occur and previously Nova would fail the entire request. With retries, Nova can be more resilient in this scenario and continue the request if a retry succeeds. Refer to https://launchpad.net/bugs/1866937 for more details.
