 +All documentation here applies to the OpenStack web interface
 +
 +===== Initial setup: add your SSH public key =====
 +
 +Go to "Compute / Key Pairs" and use "Import Public Key". You should copy/paste your SSH public key.
 +
 +You can add several public keys, and even add public keys of other admins.  These keys will be available when creating a virtual machine.

-TODO+Go to "Compute / Instances" and use "Launch Instance"
 + 
 +Most of the parameters are self-explanatory, with a few exceptions: 
 + 
 +  * **Create New Volume:** 
 +    * if enabled, an OpenStack-managed volume will be created to store the VM disk. This volume will be stored on a Ceph cluster. When deleting the VM, the volume can be kept around and attached to a new VM later on. 
 +    * if disabled, the VM disk will be stored on the same Ceph cluster but outside of OpenStack. When deleting the VM, its disk will also be deleted. This is most suitable for "throwable" virtual machines that don't store important data. 
 +  * **Networks:** use ''general_servers1'' 
 +  * **Key Pair:** select the SSH key that should be installed. It seems only a single key is accepted. 
 + 
 +===== Connect to the virtual machine ===== 
 + 
 +Look up the IP address shown in the list of instances. 
 + 
 +You can login with SSH, using your SSH key. 
 + 
 +The SSH username is usually the name of the distribution: "debian", "ubuntu", etc. If you can't find it, check the documentation of your distribution, the keywords are "openstack" and "cloud-init".
