1. A method of displaying virtual machine disks in a hierarchy, comprising: scanning a plurality of virtual machines associated with a datastore to generate a virtual machine list, the virtual machines including first and second virtual machines that share at least one virtual disk; parsing configuration data for the first virtual machine included in the virtual machine list; identifying a plurality of virtual disks corresponding to the first virtual machine based on the configuration data for the first virtual machine; examining parent/child relationships associated with the plurality of virtual disks corresponding to the first virtual machine to populate a data structure; parsing configuration data for the second virtual machine included in the virtual machine list; identifying a plurality of virtual disks corresponding to the second virtual machine based on the configuration data for the second virtual machine; examining parent/child relationships associated with the plurality of virtual disks corresponding to the second virtual machine to populate the data structure; and displaying a graphical representation of the virtual disks corresponding to the first and second virtual machines in a hierarchy using the data structure.
