Similar to USB drives, you can only attach instances to one computer at a time.

In prior OpenStack releases, volume services were provided by nova-volume, which has evolved over time into OpenStack Block Storage; that is, Cinder. OpenStack Block Storage is very similar to Amazon EC2's Elastic Block Storage—the difference is in how volumes are presented to the running instances. In OpenStack compute, volumes can easily be managed using an iSCSI-exposed LVM volume group named cinder-volumes. So, this iSCSI volume group must be present on any host running the Cinder volume service.
