This guide provides an overview and instructions for using the Vqfx-20.2r1.10-re-qemu.qcow2 file.

5. How to Use (Quick Start)

Prerequisites:

The vQFX is purpose-built for data center switching topologies. While a standard virtual router handles WAN edge routing, the vQFX handles: Vqfx-20.2r1.10-re-qemu.qcow2

A white paper or technical guide for the vqfx-20.2r1.10-re-qemu.qcow2 image would focus on its role as the Routing Engine (RE) component of Juniper's virtualized QFX10000 switch series. This image is designed for network emulation platforms like GNS3 and Containerlab to simulate complex Data Center (DC) fabrics.

    • CPU: 2–8 vCPUs recommended depending on features and scale; one should allocate at least 2 for minimal boot.
    • Memory: 8–16+ GB RAM recommended (8 GB often minimal; 12–16+ GB for feature-rich labs).
    • Disk: qcow2 size varies; allocate enough host storage for qcow2 backing file + snapshots (the file may be sparse — check with qemu-img info).
    • NICs: multiple virtual NICs (use virtio for best performance); SR-IOV or macvtap optional for direct NIC access if needed.
    • Host: Linux with QEMU/KVM support, libvirt optional.
