Create the correctly named directory under the QEMU directory: mkdir -p /opt/unetlab/addons/qemu/vmxvcp-14.1R4.8-domestic/ Use code with caution.
Security researchers analyzing old vulnerabilities (e.g., CVE-2015-7755, CVE-2016-1275) need exact versions to reproduce exploits. The 14.1R4.8 image provides a predictable, unpatched target environment for controlled testing.
Domestic (typically includes strong encryption for use within the U.S. and Canada) Format: .img (QEMU disk image) Release Status: This version is End of Life (EOL) . Usage and Configuration Jinstall-vmx-14.1r4.8-domestic.img
The name of this file tells you exactly what is inside. Breaking down the file name reveals its specific software details:
If you are a student or enthusiast, legitimate access comes through the (cloud-based) or a Juniper Learning Subscription , which provides legal access to virtual images without hosting them locally. Create the correctly named directory under the QEMU
Using in 2025/2026 carries significant risk. Juniper has publicly disclosed dozens of Critical and High severity vulnerabilities affecting Junos 14.1, including:
The 14.1r4.8 image is a favorite for emulation platforms like and GNS3 because of its relatively low resource footprint compared to modern vMX releases (which can require upwards of 12 GB of RAM per instance). Deploying in EVE-NG (Qemu) Breaking down the file name reveals its specific
: Transfer jinstall-vmx-14.1r4.8-domestic.img into that directory using an SCP client (like WinSCP or FileZilla).
Do you need assistance with for active data plane testing?
If you rely on vMX 14.1 for production, you must create a migration plan. All vMX versions prior to 19.x are end of life. The recommended minimum today is Junos 21.x or 22.x (for which the image would be named something like jinstall-vmx-22.2R1.13-domestic.img ).
The native and most efficient platform for running vMX.
