| 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. |
