This installation procedure follows the official Juniper documentation for deploying vMX on a KVM host (Ubuntu 18.04 LTS). The vMX is a system: the Routing Engine (VCP) and the Forwarding Plane (VFP) run as separate virtual machines that communicate via a virtual link. All CLI configuration is performed on the VCP, while packet forwarding and port connections are handled by the VFP.
The bundle vmxbundle-17.1R1.8.tgz is an archive for Juniper’s vMX (Virtual MX Series)

In the world of network engineering, the ability to simulate complex routing and switching environments without physical hardware is no longer a luxury—it’s a necessity. Juniper Networks’ vMX (Virtual MX Series Router) has become a gold standard for NFV (Network Functions Virtualization) testing, certification preparation (JNCIP/JNCIE), and SD-WAN prototyping.

| Issue | Likely Cause and Solution | |----------------------------------------|-----------------------------------------------------------------------------------------------------------| | VFP does not come online | Insufficient RAM allocated to VFP. Increase VFP memory to at least 8 GB (for 17.1R1.8). | | VCP or VFP fails to start | Missing bridge interfaces. Ensure br-mgmt exists and the host’s networking is properly configured. | | vmx.sh script fails with “locale” error| The script only supports English locale. Run export LANG=en_US.UTF-8 before executing the script. | | High CPU usage after boot | KSM (Kernel Same‑page Merging) may be enabled. Disable it as shown in the preparation steps. | | Package installation fails on Ubuntu 24.04| vMX is not supported on Ubuntu 24.04. Revert to Ubuntu 18.04 LTS or consider vJunos EVO. |
