Public bug reported: When nova-compute, when building and running the instance, calls spawn on virt driver, spawn can fail for several reasons.
e.g. For Ironic, the spawn call can fail if deploy callback timeout happens. If this call fails, nova-compute catches the exception, saves it for re- raising and calls shutdown_instance in a try-except block [1]. The problem is, if this shutdown_instance call also fails, a new exception 'BuildAbortException' is raised. This masks the original spawn failure. This can cause problems for Ironic where, if deployment failed due to timeout, there is a good chance that shutdown_instance will also fail due to same reason, since it involves zapping etc. So original deployment failure will not be propagated back as instance fault.
