Ifconfig –a to display list ofnetwork interfaces and their current status.

xm network –list 12345 to get the list of virtual interfaces attached to the guest.

esxlist –v 12345 to list all the network interfaces attached to the guest.

Question # 2

Which four attributes can be changed for an existing virtual machine using the edit virtual machine wizard in the Oracle VM manager? Assume that the virtual machine is not running.
