Setting up Qemu with a tap interface

Setting up Qemu with a tap interface

There are two parts to networking within QEMU:

  • The virtual network device that is provided to the guest (e.g. a PCI network card).
  • The network backend that interacts with the emulated NIC (e.g. puts packets onto the host's network).

Example: User mode network

Emulating ARM on Debian/Ubuntu

You might want to read this to get an introduction to armel vs armhf.

If the below is too much, you can try Ubuntu-ARMv7-Qemu but note it contains non-free blobs.

Running ARM programs under linux (without starting QEMU VM!)

First, cross-compile user programs with GCC-ARM toolchain. Then install qemu-arm-static so that you can run ARM executables directly on linux

If there's no qemu-arm-static in the package list, install qemu-user-static instead
