I have corrected the error! Error: Sep 18 13:53:46 gdrenterprise libvirtd: 13:53:46.116: error : virInterfaceDefParseMtu:141 : XML description for interface mtu value is improper is not well formed or invalid To correct this error you will have to remove or correct the entry of virtual IP's added to /etc/sysconfig/network-scripts/ by the virtual application. Theory! I suspect that if you add the network interface with application that have non root privileges or you have configured /etc/access.conf. In additional to running selinix, root could be the one that may have the authority to add the network interface configuration. -- Glynn D. Reynolds <glynnreynolds123(a)gmail.com&gt; GDRENTERPRISE
