Public bug reported: Description ===========
When detaching an interface that was auto-created (for example, with networks='auto' at server boot time), Nova deletes the port. Steps to reproduce ================== 1. Boot a server with an auto-created Neutron port. 2. Detach the port using the Nova API. Expected result =============== Port is detached, but still present in Neutron. While it makes sense to delete auto-created ports when deleting the server to avoid leaking ports, IMO when an auto-created port is detached its ownership now belongs to the user, as they've explicitly requested an operation on it, and are now responsible for its future life cycle. Actual result ============= The port is completely deleted from Neutron. Environment =========== Reproduced on master with a func test, reported in stable/train. ** Affects: nova Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
