bug 928521 modified nova/scheduler/manager.py to reset vm_state to ACTIVE and set task_state to None when prep_resize raises a NoHostsFound refactored run_instance and prep_resize so they don't go through _schedule and now must be implemented in driver Changed behavior to set vm_state to error on any other exception in prep_resize. Change behavior to change instance vm_state to ERROR on exceptions Added tests that the vm_state gets updated Added tests that schedule_prep_resize and schedule_run_instance have no implementation in the Driver base class Had to adjust methods and tests for Multi scheduler to reflect the new Scheduler contract Change-Id: Ibcac7ef0df3456793a2132beb7a711849510da80
