GNS3 installation in Debian 7.40

Run the following command after running su and enter password from the terminal.

apt-get install glib-2.0 pkg-config libglib2.0 build-essential libsdl1.2-dev libsdl-image1.2-dev

Download and install Qemu:

wget http://wiki.qemu-project.org/download/qemu-1.6.1.tar.bz2
tar jxvf qemu-1.6.1.tar.bz2
cd qemu-1.6.1

./configure --target-list=i386-softmmu,x86_64-softmmu
make
make install

Note:

There are several errors I have encountered when I run “make”command to prepare qemu's package. Solved by running apt-get install to install the missing applications like flex, lex and bison.

KVM Installation:

apt-get install qemu-kvm

Virtualbox installation:

To install Virtualbox, go to Applications, click Add/Remove software type virtualbox and click find. Check the OracleVM Virtualbox and click apply.

Install dependencies:

apt-get install libelf-dev uuid-dev libpcap-dev

apt-get install python-qt4 xdotool

Instead of downloading the latest GNS3 8.6 package I have downloaded and install the available Debian package repository. You can find it here: http://gns3.serverb.co.uk/

To install the packages:

dpkg -i package-name.deb

Automatically GNS3 icon will be available under the Application. Just double click and configure the necessary settings, preferences and it's ready to simulate.
