Tirado do FAQ do qemu...
User mode networking does not work: I cannot ping any IP address !
This is normal. When using user mode networking, the guest OS is behind
a virtual firewall, so that only the IP address 10.0.2.2 can be pinged.
Read the QEMU documentation for more information.

Estou tentando criar uma m�quina virtual com o qemu e que tenha placa
de rede,
mas estou tendo problemas. Para isso estou fazendo o seguinte :
- recompilei o kernel com a op��o <*> Universal TUN/TAP device driver support
ativada;
- ~# mkdir -p /dev/net
- ~# mknod /dev/net/tun c 10 200
- ~# chgrp users /dev/net/tun
- ~# chmod g+w /dev/net/tun
- ~# ifconfig tun0 192.168.0.2 up
Completando com mais informa��es.
Mesmo executando o �ltimo comando, ifconfig tun0 192.168.0.2 up, e
executando o
ifconfig
tun0 Encapsulamento do Link: Ethernet Endere�o de HW 00:FF:D9:87:44:EC
inet end.: 192.168.0.2 Bcast:192.168.0.255 Masc:255.255.255.0

Quando vou "instalar" o debian no qemu, continua aparecendo a mensagem
de erro
"warning: could not open /dev/net/tun: no virtual network emulation"
Segui o que esta na documenta��o do qemu referente a network
3.7.1 Using tun/tap network interface

Desde j� agrade�o pela aten��o.
