P2V conversion fails with the error: 'NBD_ERR_NETWORK_CONNECT' (error code:2338) (2018582)

Symptoms

  • Converting a Windows physical machine with multiple drives (such as C: and D:) using Standalone Converter fails

  • Converting the C: drive completes successfully, but converting the D: drive fails

  • P2V conversion fails at approximately 90% while converting the D: drive and you see the error:

    "FAILED: A general system error occurred: Unknown exception"

  • In the vmware-converter-worker.log file, you see entries similar to:

  • This issue occurs even if Converter is installed locally on the source machine

  • This issue occurs irrespective of whether:

    • The physical machine is converted to the same datastores or different datastores
    • The drives have been resized or not during the conversion

Resolution

This is a known issue affecting VMware vCenter Converter 4.x and VMware vCenter Converter Standalone 4.x/5.x.

To work around this issue, use Converter to convert the physical drives separately, one at a time.

For example:
  1. Convert the physical C: drive.
  2. Convert the physical D: drive.
  3. Attach the converted D: drive to the virtual machine which contains the C: drive.
  4. Power on the virtual machine.

Additional Information

This issue can also occur due to port conflicts or a port not being open. Ensure all ports are open between vCenter Server, the source machine being converted, and the ESXi/ESX hosts. For more information, see TCP and UDP Ports required to access vCenter Server, ESXi/ESX hosts, and other network components (1012382).
