I'm not sure if I understand your question, but... Qemu is using the
Linux tun/tap network device to provide a virtual ethernet NIC to the
guest OS. The tap device is subject to Linux' standard networking
configuration, i.e., is just a new NIC at the host. If you don't
configure your system for bridging (as Sven outlined) or with special
IP forwarding rules, no other machine has access to your emulated
system in Qemu.
