H A Dnet.rst3 Network emulation
6 QEMU can simulate several network cards (e.g. PCI or ISA cards on the PC
7 target) and can connect them to a network backend on the host or an
8 emulated hub. The various host network backends can either be used to
9 connect the NIC of the guest to a real network (e.g. by using a TAP
10 devices or the non-privileged user mode network stack), or to other
12 socket host network backend).
14 Using TAP network interfaces
17 This is the standard way to connect QEMU to a real network. QEMU adds a
18 virtual network device on your host (called ``tapN``), and you can then
