you can test it yourself by start building a heavy enough instance (or manually add some pauses in the code), and sigterm the nova-compute, see the difference

make it slower so that you are sure to interrupt the process in the middle
kill/restart the nova-compute when the instance is already assigned to compute, but has not been fully provisioned yet.

nova-compute[93277]: DEBUG nova.compute.manager [None req-72b47a80-146d-41d1-9a71-8b5dccf9b382 None None] [instance: 960674ab-118
3-4df9-85ae-bcb041b0d868] Instance spawn was interrupted before instance_claim, setting instance to ERROR state {{(pid=93277) _error_out_instances_whose_build_was_interrupted /opt/stack/nova/nova/compute/manager.py:1749}}

to slow down Instance start, add time.sleep(1800) in /opt/stack/nova/nova/compute/manager.py for function _do_build_and_run_instance (use AIO DevStack)
