All 5 of these SmartClone volumes are unique volumes with the original single volume occupying
space on the SAN. Each of these volumes may be introduced into the XenServer resource pool as
identified in the earlier step. A single golden image of an operating system now serves as the source
image for these 5 VMs. Modifications to the UUIDs will persist in its own volume space occupying
only what is newly written in its space on the SAN. Note that each iSCSI volume is addressed thru its
own IQN just like a regular volume.
Since SmartClones are based from a source snapshot, each VM is now managed as a single VM

new SmartClone VMs must be recreated. A single base snapshot cannot be patched to roll changes
into the SmartClones based upon that snapshot. This important distinction classifies SmartClone space
saving and instant image creations targeted towards speeding initial deployment. Note that although
