Hello Group
i running with Netbsd 6.0.1, and i have install Qemu 2.0 with one VM Server
installed with Microsft Srv, but i become (with dhcp) IP Adress 0.0.0.0.

Syntax:
qemu-system-x86_64 -m 2048 -hda /usr/Srv2003.img -net nic,model=e1000

if running command without "net nic" i have a valid from Qemu-DHCP
Address 10.0.2.15/24
here i can only ping me own address :-)

bridge, and brconfig done but without success, me aspect are that me Windows
machine can ping from bothside me network and reach the internet.

Please can you give me more help to see me misake?
Thanks
Mauri

You need to add wm0 to the bridge if you want the VM to be able to reach
the internet.

I think you will also want to give the VM a 192.168.0.x address, do you
have a DHCP server running on your network ?

Yes DHCP Server in this case are my router. i want that this Server can
be accessable from all internal network clients.
i don't know how do configure that this VM can handle any internal
network address that are serviced from me router.

Thanks for your Answer!
