contains patches for some core functions (xapi-core, xapi-xenopsd,
xapi-firmware) while XS61E010 (<a
href="http://support.citrix.com/article/CTX136253";>http://support.citrix.com/article/CTX136253</a>)
provides xentools replacement. What's more interest xentools from XS61E010
contains new and legacy drivers - new with Windows 8/Server 2012 support
while legacy - just renamed tools from XS602E009.&nbsp;In XS61E010's
installation prerequisites stated that it can't be implemented without
XS61E009.<br>
