So by default the disk of an instance is basically stored on the local
filesystem of the server where the instance is running (in
"/var/lib/nova/instances/instance-0000000X/disk"), and it's called
ephemeral because when you terminate the instance the entire directory
"/var/lib/nova/instances/instance-0000000X" gets deleted and the
virtual disk is gone, but the base image in the "_base" directory is
not touched.<o:p></o:p></span></font></p>
