Hi Sandy, virtual size is the size of the disk the VM knows, it is actually the size you chose to create it with. The true size is the summerise of all the true size which the volumes related to disk.
So for example if you have one disk of 20G and you occupied 18GB of it. Then you created a snapshot and you occupied 4GB of it, you might see that the virtual size will still be 20GB though the true size will be 22 GB You can also check in the host the commands: vdsClient 0 getVmStats <vmId> or vdsClient 0 getAllVmStats.
