 The VM is installed with the SystemVM template which is also used by the CPVM and SSVM.

 Basic operaions like Start, Stop and Reboot are allowed for troubleshooting.
 Users can access the VM using the 'View Console' button for troubleshooting although it is not
 required during normal operations.
 
 Service Offering
 ~~~~~~~~~~~~~~~~
 There are two global settings that control what should be the minimum RAM size and minimum
-CPU count for the Shared FileSystem VM : 'sharedfsvm.min.cpu.count' and 'sharedfsvm.min.ram.size`.
+CPU count for the Shared FileSystem Instance : 'sharedfsvm.min.cpu.count' and 'sharedfsvm.min.ram.size`.
 Only those offerings which meet these settings and have HA enabled are shown in the create form.
 
 Shared FileSystem Data Volume
 ~~~~~~~~~~~~~~~~~~~~~~
 The data volume is also visible to the users. It is recommended to use the Shared FileSystem UI/API to
 manage the data but users or admin can perform actions directly on the data volume or the root volume
