Cloud Consolidation Tool

Simple cloud consolidation (simulation) tool for analysis of datacenters energy consumption. Implemented consolidation algorithm computes close-to-optimum energy efficient VM placement across active cluster increasing physical hosts CPU utilization using VM live migration mechanism. Algorithm provides list of actions to be taken that can be later trigerred by DC operator.

Please note algorithm only provides a list of recommended migrations but DOES NOT actually trigger the migrations by default.

Following environment specifications are supported:

• Randomly generated environmemt specifing:
  • Total number of physical hosts
  • Total number of VMs
• Specified within provided input file
• Loaded from active OpenStack environment with active ceilometer service

Web application presents prediction of environment's energy consumption before and after consolidation.

Installation instructions

(Optionable) Install virtualenv and create virtual environment

Install virtualenv:

pip install virtualenv

Create project virtual environment:

virtualenv cloud_consol_env
source cloud_consol_env/bin/activate

Install requirements

Install project dependencies:

pip install -r requirements.txt

Init DB

Create /tmp/lmt.db file for storing results:

cd src/db/
python setup.py

Run optimization

Source your OpenStack credentials:

source admin.rc

Browse to consolidation application directory:

cd src/core/

To optimize VM placement of randomly generated environment (10 PMs, 100VMs) run:

python main.py -r 10 100

To optimize VM placement specified in input file (input_file.txt) run:

python main.py -f input_file.txt

To optimize VM placement of you running OpenStack cluster run:

python main.py

Browse results

Run Flask application:

cd src/web/
python vis_app.py
