Miniet is a software to evaluate openflow , controllers , switches and hosts.

You can use Mininet by using VM images which is provided by mininet gitgub or installing Mininet manually on Ubuntu distribution.

Here’s an example of how to deploy Mininet VMDK image within KVM.

KVM host

# kvm –version QEMU emulator version 1.2.0 (qemu-kvm-1.2.0+noroms-0ubuntu2, Debian), Copyright (c) 2003-2008 Fabrice Bellard # uname -ri 3.5.0-21-generic x86_64

download the VM image from http://mininet.github.com/download/

mininet-vm-ubuntu11.10-052312.vmware.zip

unzip the file.

$ unzip mininet-vm-ubuntu11.10-052312.vmware.zip Archive:  mininet-vm-ubuntu11.10-052312.vmware.zip   creating: Mininet-VM/  inflating: Mininet-VM/Mininet-VM.nvram  inflating: Mininet-VM/Mininet-VM.vmdk extracting: Mininet-VM/Mininet-VM.vmsd  inflating: Mininet-VM/Mininet-VM.vmx  inflating: Mininet-VM/Mininet-VM.vmxf  inflating: Mininet-VM/vmware.log  inflating: Mininet-VM/vprintproxy.log

convert the VM format to qcow2 from vmdk.

# qemu-img convert Mininet-VM.vmdk -O qcow2 Mininet-VM.qcow2

# qemu-img info Mininet-VM.qcow2 image: Mininet-VM.qcow2 file format: qcow2 virtual size: 20G (21474836480 bytes) disk size: 2.5G cluster_size: 65536

import the VM within KVM.

# virt-install --connect=qemu:///session --name mininet --ram= 512 --graphics vnc,port=5911 --disk path=./Mininet-VM.qcow2,format=qcow2 --netwo rk=bridge:br0 –import

the VM named “mininet” has been deployed within KVM.
