nbd is a "Network Block Device" driver along the lines of NFS, but it doesn't handle concurrency. https://nbd.sourceforge.io/ But it's generic, and can handle any *REGULAR* file system, not just NFS. QCOW2, or raw, or whatever, is a special QEMU format. So it requires QEMU libs (i.e. qemu-nbd) to decode QCOW2/RAW. > Why doesn't qemu have a dependency on nbd? Why doesn't qemu have a dependency on NFS? Same answer; they're both remote network block device systems that most linux users don't need, and they're both unrelated to the core functionality of QEMU. -- Walter Dnes <[email protected]> I don't run "desktop environments"; I run useful applications
