Hello,
A few days ago, I tried to use an initial backup of an existent virtual machine to create a new one (as it was a template) using vmware converter standalone 5.0 into my ESX 3.5 server. I use a new name for the new virtual machine but the process failed. The worst thing is that the original virtual machine was removed from the esx, not from the library, but from the vmfs 
¿Can you think of any reason for this has happened?
Best regards,
Miguel
