[4] By the way, if you got an image from internet, it's OK to simply add it like follows.
[root@dlp ~(keystone)]# wget cloud-images.ubuntu.com/releases/18.04/release/ubuntu-18.04-server-cloudimg-amd64.img -P /var/kvm/images 

[root@dlp ~(keystone)]# openstack image create "Ubuntu1804" --file /var/kvm/images/ubuntu-18.04-server-cloudimg-amd64.img --disk-format qcow2 --container-format bare --public
