Environment

VMware vCenter Converter Standalone 5.1.x
VMware vCenter Converter Standalone 6.0.x
VMware vCenter Converter Standalone 5.5.x

Cause

This issue occurs when the cloned drive is close to capacity. During the clone process, space is required for re-configuring the destination virtual machine. By default, there is a 10% buffer on the space required for the destination drive. If there is not enough space available due to maintain size being set for the drives, the conversion can fail.

Resolution

To resolve this issue, edit the minVolumeSizeExtraPercentage in the converter-worker.xml file to lower the percentage reserved.

1. Open the converter-worker.xml file in a plain text editor.
   
   For Windows 2003/XP:
   
   C:\Documents and Settings\All Users\Application Data\VMware\VMware vCenter Converter Standalone\
   
   For Windows 7/WindowsVista/Windows 2008/Windows 2008 R2:
   
   C:\ProgramData\VMware\VMware vCenter Converter Standalone\
   
   
2. Search for the minVolumeSizeExtraPercentage and modify the percentage to 0:
   
   For example:
   
   <minVolumeSizeExtraPercentage>0</minVolumeSizeExtraPercentage>
   
   
3. Save and close the file.
4. Restart the VMware vCenter Converter Standalone Worker service on the machine.
