I was just pointed to Flings by the VMware support team.
These apps and tools build by VMware engineers are great and already found my favorite for vCloud director.
Lctree – http://labs.vmware.com/flings/lctree
This tool is designed for the visualization of linked clone VM trees created by VMware vCloud Director when using fast provisioning.
I managed Lab Manager before and always found the build in context view feature useful to show the relationship and dependencies between virtual machines.
This helped me a lot in finding the information about shadow copies in our environment as well as the visualizing the chain length and make decisions on when to consolidate.
Applications are not supported so no fixes and use at own risk.
