This issue occurs because the provisioning stack is not being used as intended.
Note: As stated, this is being violated.
"By using the provisioning TCP/IP stack, you can isolate the traffic from the cloning operations on a separate gateway. After you configure a VMkernel adapter with the provisioning TCP/IP stack, all adapters on the default TCP/IP stack are disabled for the Provisioning traffic."
For more information, see the
VMKernel Networking Layer section of the
vSphere Networking Guide.
