The CirrOS image is limited in functionality and is recommended only for testing network connectivity and basic Compute services. Multiple vendors provide cloud-ready images for use with OpenStack, including the following:
| Canonical - Ubuntu | http://cloud-images.ubuntu.com/ |
| Red Hat - CentOS | http://cloud.centos.org/centos/ |
To install the Ubuntu 16.04 LTS image, download the file to /tmp/images and upload it to Glance:
# wget -P /tmp/images http://cloud-images.ubuntu.com/xenial/current/xenial-server-cloudimg-amd64-disk1.img
Use the openstack image create command to upload the new image:
# openstack image create "ubuntu-xenial-16.04"
--file /tmp/images/xenial-server-cloudimg-amd64-disk1.img
--disk-format qcow2 --container-format bare
--public
