I created several VMs with heat. How could I remove one specific VM using heat command? I managed to remove it with command "nova delete ...", but after that "heat stack-update" is not working normal. some error happened as below. *

Stack UPDATE FAILED (CNKP_MZ_y-base_cluster-es2e5ek45zsp): HTTPNotImplemented: resources.OAM: The requested functionality is not supported. (HTTP 501)

* So I think maybe I need to using heat to remove a specific VM if it is created by heat. But how?
