Public bug reported:
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)
