ESXi 6.5 Guest Fails to Power On After Changing Pass Through Device (Missing pciPassthru0.id entry)

Ran into a second error after swapping out a pass-through device in ESXi. This device was the same make and model as the previous device.

To resolve it, try these steps:

  1. Completely remove the old and/or new pass-through device from the Guest configuration
  2. Save the Guest configuration
  3. Confirm you are able to successfully boot the Guest without any pass-through device
  4. After the Guest starts, shut it down
  5. Add the new pass-through device to the Guest configuration.
  6. Save the Guest configuration
  7. You should now be able to boot it successfully with the new pass-through device
