GNS3 uses QEMU as a hypervisor to run VMs. The setup is similar to CML/EVE-NG but configured through the GUI.

A widely documented quirk of this specific evaluation image is that while the filename indicates version , the internal software often reports as 19.4R1.10 upon booting and running show version . Hostname: Defaults to vqfx-re .

Once the boot completes, you will be greeted with the standard login prompt: Amnesiac (ttyd0) login: root Use code with caution. Vqfx-20.2r1.10-re-qemu.qcow2

Beyond manual lab testing, this qcow2 image is a valuable asset in modern NetOps CI/CD (Continuous Integration/Continuous Deployment) pipelines. By integrating vQFX with tools like GitLab Runners, organizations can automatically spin up a virtual network, deploy a candidate Junos configuration or Ansible playbook against it, run a suite of automated tests, and then tear down the environment.

Connect the em1 interface of the RE ( vqfx-20.2R1.10-re-qemu.qcow2 ) directly to the em1 interface of the PFE node for management communication. Installation & Deployment Steps (GNS3) GNS3 uses QEMU as a hypervisor to run VMs

As the name implies, the first qcow disk is the vQFX Routing Engine (RE) and the second disk is the Packet Forwarding Engine (PFE) brezular.com Juniper vQFX - - EVE-NG

Critical Setup Tips Connectivity: You must connect the interface of the RE directly to the interface of the PFE for them to communicate. Proper Shutdown: Always use the command request system power-off
