Error deleting snapshot with VDDK 6.0 & VC / ESX 6.0

Hi ,

I am currently using VDDK 6.0 along with vSphere API to connect to a VC & ESX 6.0.

When i try to create a snapshot and delete the snapshot manually it works fine.

If I do the same thing via the APIs the create snapshot works fine. However during the deletion of the snapshot i get the following error

"An error occurred for task 'RemoveSnapshot_Task'.  Details: A general system error occurred: vim.fault.GenericVmConfigFault'."

The same code works with VDDK 5.5.4 and VC / ESX 5.5 U2.

Some how i am in the feeling that I might have to do some thing extra when talking to VC 6.0, not sure though

Can some one help me in giving me some pointers on this

Regards,

Dattu
