Hi, qemu-nbd[1] is a way to "attach" qcow2 image to a nbd[2] device, but we don't have nbd yet. Though Patrick made it working for Bitrig[3]. Would it be usable in OpenBSD?
If qemu-nbd is not an option, what are other ways to get data from various qemu-supported images (if not running qemu itself and getting data over tcp/ip)? I found vdfuse[4] but it would need VirtualBox libs working on OpenBSD...
