I'm looking for any documentation that has examples for increasing the debug level of accessing VMDKs through the VDDK. In particular I'm getting strange file permissions problems:

Insufficient permission to access file (38)

But there is not enough verbose logging to find the source, i.e. the vmdk or the -flat.vmdk. Permissions look OK.

The operations being attempted are conversions and transferring to remote hosts. It could be useful to have exact information on which file part(s), directories, or if this a source or remote host permission problem. There is not enough information on failure and many files and directories are involved.

Also if anyone has information on increasing vmware-disklib logging in either ESX 3.x or Workstation using disklib.tracelevel that would be helpful.
