nbdkit

Network Block Device server

NBD is a protocol for accessing block devices (hard disks and disk-like things) over the network. nbdkit is a toolkit for creating NBD servers. The key features are: * Multithreaded NBD server written in C. * Minimal dependencies for the basic server. * Documented plugin API with a stable ABI guarantee. Lets you to export "unconventional" block devices. * You can write plugins in C or many other languages. * Filters can be stacked in front of plugins to transform the output. 'nbdkit' is a meta-package which pulls in the core server and a subset of plugins and filters with minimal dependencies. If you want just the server, install 'nbdkit-server'. To develop plugins, install the 'nbdkit-devel' package and start by reading the nbdkit(1) and nbdkit-plugin(3) manual pages.
