Install QEMU on Ubuntu to simulate MIPSEL and run Debian

# install QEMU###

Suppose you already have an ubuntu 14 Linux:

First install qemu on ubuntu and execute the following command:

# change the line apt-get, and then install qemu

Sudo apt-get update

Sudo apt-get install qemuqemu-system

Download the corresponding image from the mips directory in http://people.debian.org/~aurel32/qemu:

Here I mark the kernel of my choice, as well as the debian image file (another image file I will error VFS mount failure when starting).

# configure virtual machine network #

1) modify the / etc/network/interfaces file in ubuntu to the following:

2) execute the following command in ubuntu to install the bridge tool and start the bridge:

Apt-get installbridge-utils

Ifup br0

3) add the following script to the ubuntu / etc/qemu-ifup file, and these instructions will be executed when qemu starts:

Echo "Executing/etc/qemu-ifup"

Echo "Bringing up $1for bridged mode..."

Sudo / sbin/ifconfig $10.0.0.0 promisc up

Echo "Adding $1 tobr0..."

Sudo / sbin/brctl addifbr0 $1

Sleep 2

The added result is as follows:

Execute the command in ubuntu to modify the contents of the / etc/sudoers file:

Sudo visudo

# add the following script at the end of the file

Cmnd_Alias QEMU = / sbin/brctl,/sbin/ifconfig

% qemu ALL=NOPASSWD: QEMU

Execute the following command to start the virtual machine in the directory where the kernel and image files are stored in ubuntu:

Sudo qemu-system-mipsel-M malta-kernel vmlinux-2.6.32-5-4kc-malta-hdadebian_squeeze_mipsel_standard.qcow2-append "root=/dev/sda1console=tty0"-net nic-net tap

If all goes well, the running window of QEMU will pop up:

The network is normal:
