How to use

sudo apt-get install 
python-pip python-yaml
sudo pip install netaddr

1. install ansible

    sudo apt-get install software-properties-common
    sudo apt-add-repository ppa:ansible/ansible
    sudo apt-get update
    sudo apt-get install ansible
   

2. clone repo

    git clone https://github.com/raddaoui/simulator.git
   

3. configure the simulator

Open the simulator user config file and configure the subnets of your pxe, management, tunnel, storage and flat networks. Then configure the dhcp pool range where VMs can take IPs, interface used by cobbler to pxeboot VMs, how many Vms you want to create per host, all already used ips by your environment, nodes where you want to create Vms, the disk in each host where your VMs will be mouned.

cd simulator
vi sim_user_config.yml

3. generate an inventory for your VMs

    python generate_sim_inv.py
   

4. Bootstrap your hosts

    cd playbooks
    ansible-playbook -i inventory/static-inventory.yml bootstrap_hosts.yml
   

5. Install cobbler in your deployment host

    cd ..
    ./setup-cobbler.sh (look for templates preseeds)
   

6. partition disk in each server and mount it to /var/lib/libvirt/

    cd playbooks
    ansible-playbook -i inventory/static-inventory.yml partition_disk.yml  
   

7. Create virsh bridged networks in your servers to which VMs will be attached

    ansible-playbook -i inventory/static-inventory.yml setup-virsh-net.yml
   

8. Create VMs

    ansible-playbook -i inventory/static-inventory.yml deploy-vms.yml
   

9. (optional): reckick all VMs to restart with a clean environment

    ansible-playbook -i inventory/static-inventory.yml rekick_vms.yml
