Converting a virtual machine to OVF format fails when the target does not support large files

Symptom:

  • While attempting to convert a virtual machine to an appliance (.OVF file) the process fails.
  • The source and destination are on the same volume, connected by USB and the file system does not support large files.
  • Conversion fails while creating the new virtual machine file.
  • The virtual machine is larger than 2GB.
  • An error appears in the Converter log:

    FAILURE TO CREATE Disk name= DiskLib error = 12
Solution:

This can because of an issue where Converter attempts to create a file that is too large for the file system and causes the file creation to fail.
To work around this issue, select a destination formatted with a file system that supports large files, such as NTFS.
