This adds a new policy rule which defaults to behave in a backward compatible way, but will allow operators to enforce that servers created with a zero disk flavor must also be volume-backed servers. Allowing users to upload their own images and create image-backed servers on local disk with zero root disk size flavors can be potentially hazardous if the size of the image is unexpectedly large, since it can consume the local disk (or shared storage pool). It should be noted that disabling the new policy rule will result in a non-backward compatible API behavior change and no microversion is being introduced for this because enforcement via a new microversion would not close the security gap on any previous microversions. Related compute API reference and user documentation is updated to mention the policy rule along with a release note since this is tied to a security bug, which will be backported to stable branches.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
