If an instance remains in an intermediate state, such as deleting, you can use the nova reset-state command to manually reset the state of an instance to an error state. You can then delete the instance. For example:

nova reset-state c6bbbf26-b40a-47e7-8d5c-eb17bf65c485
nova delete c6bbbf26-b40a-47e7-8d5c-eb17bf65c485

You can also use the –active parameter to force the instance back to an active state instead of an error state. For example:

nova reset-state --active c6bbbf26-b40a-47e7-8d5c-eb17bf65c485
