How do I bridge Android guest network traffic?

Question

I need a way to direct all traffic from an ARM Android guest to a virtual bridge on the host.

I'm using the Android emulator binaries (built from source) and Android images built from the AOSP repository.

What I have tried:

• Starting the emulator with qemu parameters to create a NIC and connect it to a host bridge (my-interface) gives a Segmentation Fault.

  emulator -avd [...] -qemu -net nic -net tap,ifname=my-interface
  

• Disabling the adbd service inside the guest did not solve the above.

From what I understand, the system uses the default interface (eth0, which is a default qemu user mode interface) for adb, which might be why I cannot replace it with a TAP interface.

Is there a way I can work around this?
