Network not detected

[Alexandre Bencz]

Hi
I just installed Debian on a QEMU virtual machine, during the 
installation, the internet connection was detected and etc, but after 
starting the system, the connection does not exist....

Ps: I'm using Windows

My QEMU command line is:
qemu-system-sparc64.exe -machine sun4u,accel=tcg,usb=off -m 2048 
-nographic -hda debian_sparc64.qcow2 -net nic,model=ne2k_pci -net 
user,hostfwd=tcp::2222-:22 -monitor telnet::4440,server,nowait -serial 
mon:telnet::3333,server,wait
