15.0.1
^^^^^^

The 15.0.1 Ocata release contains fixes for several high severity,
high impact bugs. If you have not yet upgraded to 15.0.0, it is
recommended to upgrade directly to 15.0.1.


Known Issues
************

* There is a known regression in Ocata reported in bug 1671648 where
  server build failures on a compute node are not retried on another
  compute node. The fix for this bug is being worked and will be
  provided shortly in a 15.0.2 release.

Critical Issues
***************

* Bug 1670627 is fixed. This bug led to potential over-quota errors
  after several failed server build attempts, resulting in quota usage
  to reach the limit even though the servers were deleted.

  Unfortunately the "nova-manage project quota_usage_refresh" command
  will not reset the usages to fix this problem once encountered.

  If the project should not have any outstanding resource usage, then
  one possible workaround is to delete the existing quota usage for
  the project:

     ``nova quota-delete --tenant <tenant_id>``

  That will cleanup the "project_user_quotas", "quota_usages" and
  "reservations" tables for the given project in the "nova" database
  and reset the quota limits for the project back to the defaults
  defined in nova.conf.

Bug Fixes
*********

* Fixes bug 1670522 which was a regression in the 15.0.0 Ocata
  release. For compute nodes running the libvirt driver with
  "virt_type" not set to "kvm" or "qemu", i.e. "xen", creating servers
  will fail by default if libvirt >= 1.3.3 and QEMU >= 2.7.0 without
  this fix.

   (https://bugs.launchpad.net/nova/+bug/1670522)

* Bug 1665263 is fixed. This was a regression where
  "instance.delete.start" and "instance.delete.end" notifications were
  not emitted when deleting an instance in "ERROR" state due to a
  failed build.
