Cumulus VX Getting Started Guide
Cumulus VX is free, open source software that provides a virtual experience enabling cloud and network admins to evaluate Cumulus Networks’ latest technology easily and risk free. Cumulus VX removes all organizational and economic barriers for you to get started with open networking on your own time, at your own pace and in your own environment.
You can use Cumulus VX to learn about and evaluate Cumulus Linux, anytime, anywhere. Use it to build sandbox environments for prototyping, pre-production rollouts and developing scripts.
About the Virtual Machine
Cumulus VX runs in a virtual machine (VM) on a standard x86 environment.
The VM is a 64-bit operating system, built on the same foundation as
Cumulus Linux, running
the Linux 3.2.65-1+deb7u2+cl2.5+2 kernel, using
virtio drivers for
network and HDD interfaces as well as the logical volume manager (LVM).
Four versions of the virtual disk image are available for use across various hypervisors:
An OVA disk image for use with VirtualBox.
A VMware-specific OVA disk image.
A qcow2 disk image for use with KVM.
A Box image for use with Vagrant.

Downloading the Cumulus VX Image
To get started, you need to download some software as well as the Cumulus VX disk image (qcow2 or OVA) that runs with the hypervisor you plan to use with Cumulus VX. Each disk image contains a single VM for a standalone switch. You can clone this virtual machine to build out your test network. For more information, read the appropriate steps below:
Logging in to the VM
The Cumulus VX VM has these default login credentials:
User name: cumulus
The cumulus user has
sudo privileges, just like a Cumulus Linux
