Microsoft Virtual Machine Converter fails with error: Heads values must be between 0 and 254

Symptoms

Attempting to perform a virtual machine conversion using the Microsoft Virtual Machine Converter (MVMC) solution accelerator returns the following status at completion :

Microsoft Virtual Machine Converter encountered an error while attempting to convert the virtual machine.

Details:
Heads values must be between 0 and 254.
Parameter name: value
Actual value was 255.

↑ Back to the top

Cause

This can occur if the virtual machine being converted has a GUID Partition Table (GPT) disk attached. MVMC supports converting virtual machines that have Master Boot Record (MBR) partitioned disks attached but not virtual machines that have GPT disks attached.

↑ Back to the top

Resolution

This is by design. MVMC does not currently support GPT disks.
