Cose da fare una tantum
apt-get install uml-utilities sudo modprobe tun mkdir /dev/net mknod /dev/net/tun c 10 200 tunctl
Invocare qemu (da root):
qemu -hda win98.img -boot c -net nic -net tap
Questo modo di invocare qemu dovrebbe creare un tap0:
ifconfig
...
tap1 Link encap:Ethernet HWaddr 00:FF:D1:17:42:03
inet addr:172.20.0.1 Bcast:172.20.255.255 Mask:255.255.0.0
inet6 addr: fe80::2ff:d1ff:fe17:4203/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:17 errors:0 dropped:0 overruns:0 frame:0
TX packets:112 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:500
RX bytes:1205 (1.1 KB) TX bytes:18272 (17.8 KB)
Se così non fosse assegnare un IP manualmente
ifconfig tap0 192.168.100.1 up
Configurare il client con i parametri giusti, utilizzando questo indirizzo IP come gateway.
Ricordarsi di abilitare la rete:
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE echo 1 > /proc/sys/net/ipv4/ip_forward
Premere Ctrl+Alt+{1,2,3} per entrare nelle varie modalita` di qemu.
Utile in particolare:
Ctrl+Alt+1 // Entra in modalita` comandi sendkeys ctrl-alt-f1 || ctrl-alt-backspace // Invia un comando tastiera all'emulatore

# apt-get update # apt-get install kqemu-common kqemu-source # apt-get install module-assistant # m-a prepare # m-a build kqemu # m-a install kqemu # apt-get install qemu
Creare il device
modprobe kqemu mknod /dev/kqemu c 250 0 /bin/chmod 666 /dev/kqemu
Aggiungere -usb alla linea di attivazione. Una volta dentro il sistema entrare in #modalità comandi e digitare:
usb_add host:addr
dove addr può essere scoperto con lsusb da terminale.
Su Ubuntu non sempre funziona (sulla 8.04 e 32bit non funziona). Seguire questo howto: https://bugs.launchpad.net/qemu/+bug/156085.
On Gutsy 64-bit using qemu/kvm (also VirtualBox and, I believe, VMWare) and the "-usb" switch no USB devices are available since qemu/kvm looks for the escription of them in the 'devices' file of a usbfs mount at /proc/bus/usb/ but the code previously providing the usbfs mount that is created at start-up via /etc/rcS/S11mountdevsubfs.sh --> /etc/init.d/mountdevsubfs.sh was commented out. The USB devices are now reported at /dev/bus/usb/ but currently there is no usbfs file-system mounted/linked there to provide the 'devices' text-file. qemu/kvm reports: qemuctl -qemu vdeq kvm -boot c -m 512 \\ -hda /home/all/VirtualMachines/WindowsXP-SP2.ovl -net nic,vlan=0 -soundhw es1370 -usb -net vde info usbhost Could not open /proc/bus/usb/devices $ ls -l /proc/bus/usb total 0 WORKAROUND: To re-enable it edit the file '/etc/init.d/mountdevsubfs.sh' and uncomment the code after line 40 so it reads: # Magic to make /proc/bus/usb work # mkdir -p /dev/bus/usb/.usbfs domount usbfs "" /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0644 ln -s .usbfs/devices /dev/bus/usb/devices mount --rbind /dev/bus/usb /proc/bus/usb Execute the script manually to enable the change before a system reboot: $ sudo /etc/init.d/mountdevsubfs.sh start
