[Qemu-devel] How to make TCP/IP applications run on guest OS?

[GaoYi]

Hi all,

 

   I have bridged the network of the host. There was one br0 and several taps on it. When I started up a guest using:

 

                     #kvm -hda ubuntu.img -localtime -m 1G  -net nic, -net tap,ifname=tap0,script=no

 

   The guest can ping to other VMs or physical PCs within the same LAN. However, when I tried to communicate with other VMs/PCs using TCP/IP, the incoming IP at the receiver side is the same as the host IP instead of the VM's IP. Then how to configure the network so that the TCP/IP applications run well just like the phsical PC?

 

   Thanks,

 

Yi
