[Qemu-devel] Assigning Real Network IP Address to Guest OS

[Volkan YAZICI]

Hi,

Finally I managed to install Windows Server 2003 on a Debian
GNU/Linux. Just with below configurations, network works without a touch
in the guest OS.

  host> cat /etc/network/interfaces
  # The loopback network interface
  auto lo
  iface lo inet loopback
  
  # The bridge network interface(s)
  auto br0
  iface br0 inet static
          address 192.168.1.10
          network 192.168.1.0
          netmask 255.255.255.0
          broadcast 192.168.1.255
          gateway 192.168.1.1
          bridge_ports eth0
          bridge_fd 9
          bridge_hello 2
          bridge_maxage 12
          bridge_stp off

I can make any sort of network operation on the guest OS. But what I
really want to do is to assign a static IP to the guest OS in the
192.168.1.0/24 network, to be able to access to guest OS through
machines in the same network. For this purpose, what kind of
configuration should I follow? I such an adjustment possible via
brdiging configuration? If not, I have a second NIC in the host OS
(eth1), can I use that interface for that?

I couldn't find any solutions on the qemu wiki and google. Any kind of
help will be appreciated. (Documentation pointers are welcome as well.)
