release 0.1

Overview

This script is used to create configuration files, which will be used to run VM (Virtual Machines) on Juniper's VMM infastructure.

The supported VMs are :

• VMX
• VQFX
• PC with ubuntu OS (16.04)
• PC with centos OS (7.X)

Requirement

• paramiko library (to install use pip3 install paramiko)
• yaml library

VM images

Before the script is used, the VM images must be available on the VMM.

Please upload the VM images into directory /vmm/data/user_disks/<your_user_name>

You can copy my images from /vmm/data/user_disks/irzan

Script Files

This tool consist of the following script

• vmm.py
• lib1.py
• param1.py
• lab.yaml

lib1.py

This script is the library with functions declaration used by the other scripts (vmm.py)

param1.py

This script provide the parameters required by the library

lab.yaml

This is sample configuration.

please edit this file for the following :

• the VMM pod which will be used
• the username/password to access the VMM pod
• the VM, its type, its OS, management IP address and network interfaces for connection to other devices.

Please refer to the sample configuration

vmm.py

This script is the user interface, which will read the configuration lab.yaml and call the library from `lib1.py1

There are different arguments required by this script

• argument upload : to create VMM configuration files and upload them into VMM pod
• argument start : to start the topology inside the VMM
• argument stop : to stop the topology inside the VMM
• argument get_serial : to get serial console information of the active VMs in the VMM

Caution

• when the script is used to start the topology, any existing running topology will be stopped and unbound. Please backup the existing topology if needed.
• this script will need a GW which will be assigned with IP address from juniper's VMM lab. The rest of the VMs (devices), their management will be connected to virtual network behind the GW.
• to access the other devices (other than GW), VM GW can be used as jump host, or VM GW can be configured as VPN server using wireguard or openvpn
