  <li>an <strong>hypervisor</strong> is a layer of software allowing to
    virtualize a node in a set of virtual machines with possibly different
    configurations than the node itself</li>

generic layer to manage domains on a node.</p><p>This implies the following:</p><ul><li>the API should not be targetted to a single virtualization environment
    though Xen is the current default, which also means that some very
    specific capabilities which are not generic enough may not be provided as
    libvir APIs</li>
  <li>the API should allow to do efficiently and cleanly all the operations
    needed to manage domains on a node</li>
  <li>the API will not try to provide hight level multi-nodes management
    features like load balancing, though they could be implemented on top of
    libvir</li>
</ul><p>So libvir should be a building block for higher level management tools or
for applications focusing on virtualization on a single node (the only
exception being domain migration between node capabilities which may need to
be added at the libvir level)</p><p> </p><p></p></div></div><div class="linkList2"><div class="llinks2"><h3 class="links2"><span>main menu</span></h3><ul><li><a href="index.html">Home</a></li><li><a href="news.html">Releases</a></li><li><a href="intro.html">Introduction</a></li><li><a href="architecture.html">libvir architecture</a></li><li><a href="downloads.html">Downloads</a></li><li><a href="FAQ.html">FAQ</a></li><li><a href="bugs.html">Reporting bugs and getting help</a></li><li><a style="font-weight:bold" href="html/index.html">API Menu</a></li><li><a href="ChangeLog.html">Recent Changes</a></li></ul></div><div class="llinks2"><h3 class="links2"><span>related links</span></h3><ul><li><a href="https://www.redhat.com/archives/libvir-list/">Mail archive</a></li><li><a href="http://www.cl.cam.ac.uk/Research/SRG/netos/xen/index.html">Xen project</a></li><li><form action="search.php" enctype="application/x-www-form-urlencoded" method="get"><input name="query" type="text" size="12" value="Search..." /><input name="submit" type="submit" value="Go" /></form></li><li><a href="http://xmlsoft.org/"><img src="Libxml2-Logo-90x34.gif" alt="Made with Libxml2 Logo" /></a></li></ul></div></div><div id="bottom"><p class="p1"></p></div></div></body></html>
