             Summary: ListUsage API always displays the Virtual size as '0' for Usage type=9 (snapshot)
                 Key: CLOUDSTACK-10060
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-10060
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
            Reporter: Pranali Mande

*Bug Description:*
In the listUsage API, the Virtual Size of Snapshot is always displayed as '0'.

*Root Cause: *
In case of snapshots, the usage is accounted for depending on the value of the global parameter, 'usage.snapshot.virtualsize.select'. If set to 'true', the usage is done based on the Virtual Size, and if set to false, it is done based on the Physical size. This value, (i.e. virtual or physical) is displayed as 'Size' field in the Usage API and the field 'VirtualSize' is always displayed as 0.

*Expected Output:*
Since this is a Usage API, ideally only that size should be displayed which is used for billing, depending on the value of 'usage.snapshot.virtualsize.select'.

The ListSnapshot API displays both, the physical as well as Virtual size and that can be used to know both the sizes.
