Hi Kanagaraj,
AFAICT, there is no bug here.
if not CONF.allow_resize_to_same_host:
filter_properties['ignore_hosts'].append(instance['host'])
else:
filter_properties['force_nodes'] = [instance['node']]
When allow_resize_to_same_host is True, then filter_properties['force_node']
will be set to a list with only one node (the compute node that the instance is
currently on), and therefore the resize will happen on the original host.
Best,
