As of VDDK 6.7.1, logging is available to help diagnose behavior of the VixMntapi library. Currently this facility is available for Linux but not Windows.

The output file is named vixMntapi.log and appears in the same directory as other log files, as set by the tmpDirectory line in the VDDK configuration file passed as the seventh parameter to VixDiskLib_InitEx. Logging levels are the same as for vixDiskLib.transport:

  • 0 = Panic (failure)
  • 1 = Error
  • 2 = Warning
  • 3 = Audit
  • 4 = Info
  • 5 = Verbose
  • 6 = Trivia
