We are amped to announce the release of: nova 14.0.4: Cloud computing fabric controller This release is part of the newton stable release series. Download the package from: https://tarballs.openstack.org/nova/ For more details, please see below. 14.0.4 ^^^^^^ Known Issues ************ * When generating Libvirt XML to attach network interfaces for the *tap*, *ivs*, *iovisor*, *midonet*, and *vrouter* virtual interface types Nova previously generated an empty path attribute to the script element (*<script path=''/>*) of the interface. As of Libvirt 1.3.3 (commit) and later Libvirt no longer accepts an empty path attribute to the script element of the interface. Notably this includes Libvirt 2.0.0 as provided with RHEL 7.3 and CentOS 7.3-1611. The creation of virtual machines with offending interface definitions on a host with Libvirt 1.3.3 or later will result in an error "libvirtError: Cannot find '' in path: No such file or directory". Additionally, where virtual machines already exist that were created using earlier versions of Libvirt interactions with these virtual machines via Nova or other utilities (e.g. *virsh*) may result in similar errors. To mitigate this issue Nova no longer generates an empty path attribute to the script element when defining an interface. This resolves the issue with regards to virtual machine creation. To resolve the issue with regards to existing virtual machines a change to Libvirt is required, this is being tracked in Bugzilla 1412834 (https://libvirt.org/git/?p=libvirt.git;a=commit;h=9c17d665fdc5f0a b74500a14c30627014c11b2c0) (https://bugzilla.redhat.com/show_bug.cgi?id=1412834) Bug Fixes ********* * Fixes bug 1662699 which was a regression in the v2.1 API from the "block_device_mapping_v2.boot_index" validation that was performed in the legacy v2 API. With this fix, requests to create a server with "boot_index=None" will be treated as if "boot_index" was not specified, which defaults to meaning a non-bootable block device.
