libguestfs
open-in-new
<h2 id="structure">Structure</h2> <p>libguestfs is only one part of the larger libguestfs project. Each of the following is a separate source code archive (tarball):<a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a> </p> <ul><li>libguestfs, the library.</li> <li>guestfs-tools, the command-line programs making use of libguestfs.</li> <li>hivex, the Windows Registry editing library (with command-line programs).</li> <li>libnbd, userspace library providing a <a href="/facts/Network_block_device/wQhMfwag">network block device</a> client.</li> <li>nbdkit, code for a network block device server.</li> <li>supermin, tools for creating "appliances".</li> <li>virt-p2v, tool for converting a physical machine into a KVM instance.</li> <li>virt-v2v, tool for converting a non-KVM hypervisor instance into a KVM instance.</li></ul> <p>Some of these components (nbd-related and hivex) are created separately by libguestfs authors because they are needed for implementing some features in libguestfs, but can also be used independently of the image-handling functionality. Others are tools that build on libguestfs but go beyond its original scope. </p> <h3>Hivex</h3> <p>Hivex is a C library from the authors, intended for reading and writing <a href="/facts/Windows_Registry/cH9RlHTp">Windows Registry</a> Hive files. It comes with a number of console programs for processing these files. Hivex itself does not deal with virtual machine images. For editing files in VM images, libguestfs ships a program called "virt-win-reg".<a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a> </p> <h2 id="see-also">See also</h2> <ul> <li>Free and open-source software portal</li></ul> <ul><li><a href="/facts/Kernel-based_Virtual_Machine/d6eSuTuK">Kernel-based Virtual Machine</a> (KVM)</li> <li><a href="/facts/QEMU/s6utqULJ">QEMU</a></li> <li><a href="/facts/Libvirt/9YwAkRsr">libvirt</a></li> <li><a href="/facts/OpenStack/bAfb8KVQ">OpenStack</a></li> <li><a href="/facts/Linux_range_of_use/7Lch3I2y">Linux range of use § Virtualization</a></li></ul> <h2 id="external-links">External links</h2> <ul><li><a href="http://libguestfs.org/">Official website</a></li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>"Description from home page". <a href="http://libguestfs.org/" target="_blank">http://libguestfs.org/</a> <a href="#fnref:1" class="footnote-back-ref">↩</a></p></li> <li id="fn:2"><p>"A reminder why you should never mount guest disk images on the host OS". <a href="https://www.berrange.com/tags/libguestfs/" target="_blank">https://www.berrange.com/tags/libguestfs/</a> <a href="#fnref:2" class="footnote-back-ref">↩</a></p></li> <li id="fn:3"><p>"Description from home page". <a href="http://libguestfs.org/" target="_blank">http://libguestfs.org/</a> <a href="#fnref:3" class="footnote-back-ref">↩</a></p></li> <li id="fn:4"><p>"Description from home page". <a href="http://libguestfs.org/" target="_blank">http://libguestfs.org/</a> <a href="#fnref:4" class="footnote-back-ref">↩</a></p></li> <li id="fn:5"><p>"Features in Fedora 12". <a href="https://fedoraproject.org/wiki/Fedora_12_Alpha_release_notes#New_Virtualization_Features" target="_blank">https://fedoraproject.org/wiki/Fedora_12_Alpha_release_notes#New_Virtualization_Features</a> <a href="#fnref:5" class="footnote-back-ref">↩</a></p></li> <li id="fn:6"><p>"Description from home page". <a href="http://libguestfs.org/" target="_blank">http://libguestfs.org/</a> <a href="#fnref:6" class="footnote-back-ref">↩</a></p></li> <li id="fn:7"><p>"Manual page guestfs-performance(1): engineering libguestfs for greatest performance". libguestfs.org. <a href="https://libguestfs.org/guestfs-performance.1.html" target="_blank">https://libguestfs.org/guestfs-performance.1.html</a> <a href="#fnref:7" class="footnote-back-ref">↩</a></p></li> <li id="fn:8"><p>"Manual page guestfs(3), sections "backend" and "backend settings"". <a href="http://libguestfs.org/guestfs.3.html#backend" target="_blank">http://libguestfs.org/guestfs.3.html#backend</a> <a href="#fnref:8" class="footnote-back-ref">↩</a></p></li> <li id="fn:9"><p>https://download.libguestfs.org/ <a href="https://download.libguestfs.org/" target="_blank">https://download.libguestfs.org/</a> <a href="#fnref:9" class="footnote-back-ref">↩</a></p></li> <li id="fn:10"><p>https://libguestfs.org/hivex.3.html <a href="https://libguestfs.org/hivex.3.html" target="_blank">https://libguestfs.org/hivex.3.html</a> <a href="#fnref:10" class="footnote-back-ref">↩</a></p></li> </ol>
