Comment 2 for bug 1646841

2016-12-02 20:30:37.299 28333 DEBUG nova.compute.manager [req-35a8b9f0-f515-4c01-bd83-8cc0b3a59403 - - - - -] [instance: 7a31c72f-6f9a-4c94-9719-1c3ccb6ed117] Instance in transitional state resize_prep at start-up clearing task state _init_instance /usr/lib/python2.7/site-packages/nova/compute/manager.py:840

with debug on, I think I can confirm this is a race condition, the init process wrongly think the status is transitional , actually it's API layer just modified
