The qcow2 file will need to be copied into your project working directory, from where the container instances will be launched. Keep the qcow2 image and get rid of the rest from the extracted tar file. You can pick any version from 17.1 onwards, including service releases:

Once the system is back, check the allocated hugepages:ĭownload the latest vmx-bundle-x.y.tgz (18.2R1 at the time I published this post) from and extract the qcow2 image. GRUB_CMDLINE_LINUX_DEFAULT="nomodeset consoleblank=0 default_hugepagesz=1G hugepagesz=1G hugepages=8" This can be done with page sizes of 2MB or 1GB and is best done via kernel options in /etc/default/grub (example shows 8 x 1GB): If your host has 16GB, you can dedicate e.g. Count 1GB per vMX instance, but make sure you leave at least 50% to all other applications.

The last command will add your userid to the docker group, allowing you access to docker commands without sudo.Įnable hugepages.

Update and install the required software (example shown for Ubuntu bionic, adjust accordingly): Install or update the latest Linux distribution of choice to your server. Everything the vMX needs to run, is provided by the docker Container. They won’t interfere with the containers. No need to install qemu-kvm, nor virsh, nor else, but don’t worry if you happen to have these installed.

Docker engine, Docker compose, git and make installed.

junos-vmx-x86–64–17.3R1.10.qcow2 image, extracted from the vmx-bundle-*tgz file available at or as an eval download from (registration required).

Provisioned Memory Hugepages (1GB per vMX instance).

Running this within a Virtual Machine however isn’t an option, not just for the dismal overall performance for running nested VM’s.

Any recent Linux baremetal server with at least 4GB of RAM and a CPU built in the last 4 years (Ivy Bridge and newer) with KVM acceleration support.

Which Linux distribution you might ask? Well, I’ve used Ubuntu up to bionic (18.04) and Debian 9, but any other recent distribution should work equally well. The only host software package dependencies left to be installed by you are git, make, docker.io and docker-compose. They all share the use of the pre-built and published Docker container juniper/openjnpr-container-vmx combined with configuration files and containerized helper application, orchestrated via a docker-compose.yml file (and the externally sourced vMX control plane QCOW2 images).

Readers familiar with the vMX structure of using two virtual machines, one for the control plane (VCP) and another for the forwarding engine (VFP) might have spotted an error in the previous paragraph: how can one deploy a fully functional vMX by only providing the control plane virtual image? Well, this is actually possible, because the actual forwarding engine is downloaded at runtime from the control plane into the VFP, or in the container age, straight into the Container! Use casesīefore I dive into the nitty gritty details on how the container actually works and how to use it, I’d like to point to a few use cases I built and published recently: You do need to “bring your own” licensed Juniper vMX KVM bundle from the official Juniper download site. Well, this is now possible via pre-built Docker Containers, juniper/openjnpr-container-vmx, capable of launching any vMX qcow2 image from release 17.1 onwards. Why can’t I just get a Docker Container with the vMX deployed using Docker, Docker Compose or Kubernetes? This would allow me to launch a fully virtualized topology with routers and endpoints with a single docker-compose command, try something out, redeploy with different Junos versions and even share the recipe with other users via public Git repo’s.

But the software dependencies combined with manual editing and launch of shell scripts per vMX instance felt a bit outdated to me. Being able to download and run Juniper vMX on KVM and ESXi has really helped me learning more about networking, telemetry and build automation solutions.
