 ===== Tasks ======
+<note warning>
+All VM names must contain your username. Replace ''user.name'' with your own username (e.g. ''john.doe'') in the following tasks. If the VM name is not specified or is generic (e.g. ''scgc'', ''vm1''), append your username to them (e.g. ''john.doe.scgc'', ''john.doe.vm1'').

 ==== 1. [10p] Authentication ====
 Before using the clients, we must provide the necessary authentication parameters. This is done via an OpenStack RC file.
