+The default image size quota of 1GiB may be too small if larger images
+are to be used. Change the default at setup time with:
+
+::
+
+ GLANCE_LIMIT_IMAGE_SIZE_TOTAL=5000
+
+or at runtime via:
+
+::
+
+ openstack --os-cloud devstack-system-admin registered limit update \
+ --service glance --default-limit 5000 --region RegionOne image_size_total
