Mitaka Series Release Notes¶
13.3.13¶
New Features¶
The nova SSH public key distribution has been made a lot faster especially when deploying against very large clusters. To support larger clusters the role has moved away from the “authorized_key” module and is now generating a script to insert keys that may be missing from the authorized keys file. The script is saved on all nova compute nodes and can be found at
/usr/local/bin/openstack-nova-key.sh
. If ever there is a need to reinsert keys or fix issues on a given compute node the script can be executed at any time without directly running the ansible playbooks or roles.
13.3.8¶
New Features¶
The os_nova role can now deploy the a custom /etc/libvirt/qemu.conf file by defining
qemu_conf_dict
.
13.3.0¶
Upgrade Notes¶
Adding a new nova.conf entry, live_migration_uri. This entry will default to a
qemu-ssh://
uri, which uses the ssh keys that have already been distributed between all of the compute hosts.
Cleanup tasks are added to remove the nova console git directories
/usr/share/novnc
and/usr/share/spice-html5
, prior to cloning these inside the nova vnc and spice console playbooks. This is necessary to guarantee that local modifications do not break git clone operations, especially during upgrades.
13.1.3¶
Bug Fixes¶
The
/var/lib/libvirt/qemu/save
directory is now a symlink to{{ nova_system_home_folder }}/save
to resolve an issue where the default location used by the libvirt managed save command can result with the root partitions on compute nodes becoming full whennova image-create
is run on large instances.
