in migration/infrared/tripleo-ovn-migration/roles/create-resources/templates/create-resources.sh.j2 curl command is running as follows:

curl -o cirros-0.4.0-x86_64-disk.img http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img

This does not work, see below:


(overcloud) [stack@undercloud-0 ~]$ curl -o cirros-0.4.0-x86_64-disk.img http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img
