Once the VM is provisioned and linked to a companion VFP instance via internal bridge interfaces (usually mapping fxp0 and the internal communication links), power on the VCP node.
Are you deploying this as a or linking it to a VFP data-plane instance ? What routing features or protocols are you trying to test?
For stable performance in GNS3, users typically allocate approximately 2 GB to 2.5 GB of RAM .

Mastering Juniper vMX: Deployment and Configuration Guide for Jinstall-vmx-14.1r4.8-domestic.img Introduction
The VCP runs the Junos OS routing engine. It handles all routing protocols (OSPF, BGP, IS-IS), system management (SSH, Netconf, SNMP), and state calculations. The jinstall-vmx-14.1r4.8-domestic.img predominantly serves as the operating software for this control engine. The Virtual Forwarding Plane (VFP) Once the VM is provisioned and linked to

. In later iterations of the vMX (v15.1 and above), Juniper transitioned to a dual-node system where the Virtual Control Plane (vCP) and Virtual Forwarding Plane (vFP) run as two distinct virtual machines.
However, the 14.1R4.8 version integrates both planes into a single image. This offers several advantages for lab environments: Resource Efficiency For stable performance in GNS3, users typically allocate
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)
While useful, it is important to note the limitations of version 14.1R4.8:
Because it combines the routing and forwarding functions into a single VM, it is highly lightweight. It can run on as little as 1 vCPU and 1024 MB of RAM
At least 2 virtual network interfaces (NICs)—one for out-of-band management ( fxp0 ) and one or more for revenue/data ports. Deployment Architectures
