+	  QEMU is a generic and open source machine emulator and
+	  virtualizer.
+
+	  When used as a machine emulator, QEMU can run OSes and
+	  programs made for one machine (e.g. an ARM board) on a
+	  different machine (e.g.  your own PC). By using dynamic
+	  translation, it achieves very good performance.
+
+	  When used as a virtualizer, QEMU achieves near native
+	  performances by executing the guest code directly on the
+	  host CPU. QEMU supports virtualization when executing under
+	  the Xen hypervisor or using the KVM kernel module in
+	  Linux. When using KVM, QEMU can virtualize x86, server and
+	  embedded PowerPC, and S390 guests.

+	help
+	  Enable user mode network stack, which is the default
+	  networking backend. It requires no administrator privileges
+	  and generally is the easiest to use but has some
+	  limitations:
+
+	  - there is a lot of overhead so the performance is poor;
+	  - in general ICMP does not work (can't ping from/to a guest)
+	  - on Linux hosts, ping does work from within the guest, but it
+	    needs initial setup by root (once per host)
+	  - the guest is not directly accessible from the host or the
+	    external network
+
+	  User Networking is implemented using "slirp", which provides a
+	  full TCP/IP stack within QEMU and uses that stack to implement
+	  a virtual NAT'd network.
+
+	  Notice that this option does not disable other networking
+	  modes.
