`diskDeviceKey` is `VirtualDisk.key` from `vm.config.hardware.device`
(2000 for Hard disk 1). The replacement resolves it from the datastore
path when `open` is given a VMDK rather than a key. That path may be
the current leaf or a parent in `backing.parent` (snapshot deltas such
as `…-000007.vmdk` after the VM has moved on to `…-000008.vmdk`). The
ticket still uses the device key; `OPEN_FILE` then names the snapshot
file.
(2000 for Hard disk 1). Read-only `VixDiskLib_Open` does **not** send
it: the drop-in uses `NfcGetVmFiles` and puts the VMDK path (leaf or
snapshot parent) only on NFC `OPEN_FILE`. Writable `open` resolves a
key from the datastore path, matching the current leaf or any parent
in `backing.parent` (for example `…-000007.vmdk` after the VM has
moved on to `…-000008.vmdk`).
