Public bug reported:

OpenStack version: Antelope

In /etc/cinder/cinder.conf added below line:
use_multipath_for_image_xfer = True

In /etc/nova.conf and nova-cpu.conf added below line:
volume_use_multipath = True

Used cinder as backend for glance.
In /etc/glance/glance-api.conf added below lines:
[glance_store]
stores = cinder, file, http, swift
default_store = cinder

[cinder]
cinder_store_auth_address = http://10.x.y.z/identity
cinder_store_user_name = cinder
cinder_store_password = passwd
cinder_store_project_name = service
cinder_store_use_multipath = True

multipath is running:
stack@bay02:~$ sudo multipathd show status
path checker states:
up                  1

paths: 0
busy: False
stack@bay02:~$

Executed below command:
openstack image create --disk-format qcow2 --file cirros-0.6.2-x86_64-disk.img cirros_x

In logs, we observe that multipath is False in connector object
