The libvirt C# bindings class library exposes the Libvirt namespace. . Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It is free software available under the GNU Lesser General Public License. At their simplest, containers can just be thought of as a collection of processes, separated from the main host processes via a set of resource namespaces libvirt APIs use a basic request/response architecture that is generally synchronous libvirt application calls a libvirt API (the request) which doesn't return until the action is . This API solves the race inherent between virConnectListNetworks and By default, the libvirtd daemon listens for requests on a local Unix domain socket. For example, the command 'virsh list --all' can be used to list the existing The libvirt LXC driver manages "Linux Containers".
