Howto install Qemu in Ubuntu Hardy

This howto explains how to install qemu virtualizer in a Ubuntu Hardy system.

First of all we install qemu itself.

$sudo apt-get install qemu

Right now qemu would work only as an emulator. Installing kqemu will make it to work as a virtualizer:

We install kqemu sources to compile a kernel module.

$sudo apt-get install kqemu-source kqemu-common

NOTE: If our user does not pertain to src group we have to add it to access /usr/src directory.

$sudo adduser `whoami` src

Before compiling kqemu sources we need some previous packages:

$sudo apt-get install gcc libc6-dev

$sudo apt-get install "linux-headers-$(uname -r)"

$cd /usr/src

$sudo ln -s linux-headers-$(uname -r) linux

Now we uncompress and compile kqemu sources:

$tar xvfj kqemu.tar.bz2

$cd modules/kqemu

$./configure

$make

$sudo make install

RUNNING QEMU

We load kqemu kernel module

$sudo modprobe kqemu

and then we can execute qemu as a virtualizer. E.g:

$sudo qemu -m 128 -hda /dev/sda -cdrom debian-40r5-i386-businesscard.iso -boot d
