We are overjoyed to announce the release of: nova 21.1.0: Cloud computing fabric controller This release is part of the ussuri 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. 21.1.0 ^^^^^^ Upgrade Notes ************* * When using file-backed memory, the "nova-compute" service will now fail to start if the amount of reserved memory configured using "[DEFAULT] reserved_host_memory_mb" is equal to or greater than the total amount of memory configured using "[libvirt] file_backed_memory". Where reserved memory is less than the total amount of memory configured, a warning will be raised. This warning will become an error in a future release. The former combination is invalid as it would suggest reserved memory is greater than total memory available, while the latter is considered incorrect behavior as reserving of file-backed memory can and should be achieved by reducing the filespace allocated as memory by modifying "[libvirt] file_backed_memory". Bug Fixes ********* * A new "[workarounds]/reserve_disk_resource_for_image_cache" config option was added to fix the bug 1878024 where the images in the compute image cache overallocate the local disk. If this new config is set then the libvirt driver will reserve DISK_GB resources in placement based on the actual disk usage of the image cache. (https://bugs.launchpad.net/nova/+bug/1878024) * Previously, attempting to configure an instance with the "e1000e" or legacy "VirtualE1000e" VIF types on a host using the QEMU/KVM driver would result in an incorrect "UnsupportedHardware" exception. These interfaces are now correctly marked as supported.
