This is intended by design : we don't want the compute manager to hardstop on an exception, but we rather want to have the instance going into an ERROR state with the proper exception handling [1]
Since the libvirt driver exposes the fact that it can't resize on the same host, that's why allow_resize_to_same_host shouldn't be never set to True with this driver, unless for very specific debugging or testing cases.

Status in OpenStack Compute (nova): Won't Fix Bug description: Migrate the instance, the destination host is not specified.
