You can log in guest and use command: "ip link show" to get the value of N. Then create ifcfg-ethN for it and use "ifup ethN" to start it in guest. <blockquote cite="mid:0A8CFEC45B7F4C419F7543867C47442307697CB8@mailserver.nechclst.in" type="cite"> <div class="Section1"> <o:p></o:p> <o:p> </o:p> Guest eth interface does not create.
