Closing this as WontFix since it works as expected, and keeping it open
as wishlist item does not make too much sense.
The QEMU project normally doesn't implement new features like these
external snapshots on demand; they're a lot of work to do. Instead we
simply code-review and incorporate such features as and when people
decide to write them and submit the patches. So there's not much point
in having a 'wishlist' bug in the bug tracker saying "support for
feature X would be nice", because it will likely never happen, unless by
the coincidence that somebody happened to implement and submit it to us
anyway. Sorry for the inconvenience and thanks for your understanding.

Title:
qemu-nbd: always first snapshot loaded from VDI images with snapshots
Status in QEMU:
Won't Fix
Bug description:
When mounting a virtual box disk image of a VM with snapshots, always
the state of the first snapshot is shown.
How to reproduce:
1. Create a new VirtualBox VM or use an existing one, while choosing VDI as
the disk image format.
2. Create a snapshot of the VM.
3. Modify the file system from within the VM enough that differences to the
snapshotted version are apparent.
4. Create another snapshot.
5. Shut down the VM.
6. Mount the partition from the disk image with `qemu-nbd -c /dev/nbd0
/path/to/disk.vdi; mount /dev/nbd0pX /mnt`
Expected result: The mounted disk image shall represent the latest state of
the VM
Actual result: The mounted disk image represents the VM state at the first
snapshot
version information: qemu-nbd-2.11.1(openSUSE Tumbleweed)
