Main issue is with ImagePropertiesFilter, but it may cause issues with combination of flavor/image (for example allows to run license restricted OS (Windows) on host which has no such license, or rebuild instance with cheap flavor with image which is restricted only for high-priced flavors). I don't know if this is a security bug or not, if you would find it non-security issue, please remove the security flag. Steps to reproduce: 1. Set up nova with ImagePropertiesFilter or IsolatedHostsFilter active. They should allows to run 'image1' only on 'host1', but never on 'host2'. 2. Boot instance with some other (non-restricted) image on 'host2'. 3. Use nova rebuild INSTANCE image1 Expected result: nova rejects rebuild because given image ('image1') may not run on 'host2'. Actual result: nova happily rebuild instance with image1 on host2, violating restrictions. Checked affected version: mitaka. I believe, due to the way 'rebuild' command is working, newton and master are affected too.
