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.

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.
