configuring my wireless network card to allow Qemu/KVM guests to act as if they have a bridged network interface rather then NAT

I'm trying to configure a full desktop system based on Debian Squeeze for Armel emulated with Qemu/KVM on top of Ubuntu 15.04 64 bit. I have created a shell script like this : qemu-system-arm -M versatilepb -kernel vmlinuz-3.2.0-4-versatile -initrd [login to view URL] -hda [login to view URL] -append "root=/dev/ram" when I run the script the installation of debian starts,but it stops when it tries to connect to internet using the ethernet card but it does not work because on the campus university I can't use it and without the internet connection active I can't complete the debian for armel installation. Infact I'm connected with the USB wireless driver named "802.11g USB WLAN Card ; driver=rt73usb". My ethernet card is named "RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller ; driver=r8169". This is the network configuration of my linux workstation : root@ziomario-Z87-HD3:/home/ziomario/Scrivania/Arm# ifconfig eth0 Link encap:Ethernet IndirizzoHW UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisioni:0 txqueuelen:1000 Byte RX:0 (0.0 B) Byte TX:0 (0.0 B) lo Link encap:Loopback locale indirizzo inet:[login to view URL] Maschera:[login to view URL] indirizzo inet6: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:100755 errors:0 dropped:0 overruns:0 frame:0 TX packets:100755 errors:0 dropped:0 overruns:0 carrier:0 collisioni:0 txqueuelen:0 Byte RX:21363513 (21.3 MB) Byte TX:21363513 (21.3 MB) virbr0 Link encap:Ethernet IndirizzoHW indirizzo inet:[login to view URL] Bcast:[login to view URL] Maschera:[login to view URL] UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:1 errors:0 dropped:0 overruns:0 carrier:0 collisioni:0 txqueuelen:0 Byte RX:0 (0.0 B) Byte TX:79 (79.0 B) wlan0 Link encap:Ethernet IndirizzoHW indirizzo inet:[login to view URL] Bcast:[login to view URL] Maschera:[login to view URL] indirizzo inet6: fe80::20e:8eff:fe19:8c4b/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1565853 errors:0 dropped:0 overruns:0 frame:0 TX packets:556280 errors:0 dropped:0 overruns:0 carrier:0 collisioni:0 txqueuelen:1000 Byte RX:896937722 (896.9 MB) Byte TX:64330498 (64.3 MB) Here you can see where I have got the files that I've used inside the script : vmlinuz-3.2.0-4-versatile --> [login to view URL]~aurel32/qemu/armel/vmlinuz-3.2.0-4-versatile [login to view URL] --> [login to view URL] and I've renamed it to [login to view URL] [login to view URL] --> qemu-img create -f qcow [login to view URL] 10G this is what says the "route" command : root@mariuccio-Z87-HD3:/home/mariuccio/Scrivania/Arm# route Tabella di routing IP del kernel Destination Gateway Genmask Flags Metric Ref Use Iface default [login to view URL] 0.0.0.0 UG 1024 0 0 wlan0 [login to view URL] * [login to view URL] U 0 0 0 lxcbr0 link-local * [login to view URL] U 1000 0 0 wlan0 [login to view URL] * [login to view URL] U 0 0 0 wlan0 [login to view URL] * [login to view URL] UH 0 0 0 tap0 [login to view URL] * [login to view URL] U 0 0 0 virbr0
