Projects / libvirt


Libvirt is a library for management of virtualized operating systems. Initially supporting the Xen hypervisor, it provides a generic driver backend to allow implementations for management of arbitrary hypervisors (QEMU, UML, etc). The library aims to provide a long term stable API to isolate applications from instability in the APIs of the underlying virtualization technology. The core library API is written in C, with bindings for Python and a command line tool for shell scripting also provided. The library allows either full read-write access to the hypervisor, or for unprivileged use a secure read-only channel (eg for monitoring).
