We enthusiastically announce the release of: nova 20.5.0: Cloud computing fabric controller This release is part of the train 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. 20.5.0 ^^^^^^ Upgrade Notes ************* * The default for "[glance] num_retries" has changed from "0" to "3". The option controls how many times to retry a Glance API call in response to a HTTP connection failure. When deploying Glance behind HAproxy it is possible for a response to arrive just after the HAproxy idle time. As a result, an exception will be raised when the connection is closed resulting in a failed request. By increasing the default value, Nova can be more resilient to this scenario were HAproxy is misconfigured by retrying the request. Bug Fixes ********* * Fixes bug 1892361 in which the pci stat pools are not updated when an existing device is enabled with SRIOV capability. Restart of nova-compute service updates the pci device type from type-PCI to type-PF but the pools still maintain the device type as type-PCI. And so the PF is considered for allocation to instance that requests vnic_type=direct. With this fix, the pci device type updates are detected and the pci stat pools are updated properly. (https://bugs.launchpad.net/nova/+bug/1892361) Other Notes *********** * The nova libvirt virt driver supports creating instances with multi- queue virtio network interfaces. In previous releases nova has based the maximum number of virtio queue pairs that can be allocated on the reported kernel major version. It has been reported in bug #1847367 that some distros have backported changes from later major versions that make major version number no longer suitable to determine the maximum virtio queue pair count. A new config option has been added to the libvirt section of the nova.conf. When defined nova will now use the "[libvirt]/max_queues" option to define the max queues that can be configured, if undefined it will fallback to the previous kernel version approach.
