Unlike standard virtual routers like vSRX or modern unified images like vJunos-switch , the legacy requiring two separate virtual machines to function as a single switch:
<vcpu placement='static' cpuset='2-3'>2</vcpu>
Network engineers often hunt for this specific version because of its balance between resources and features. vqfx202r110reqemuqcow2 top

To run the vQFX 20.2R1.10 RE image stably inside QEMU, apply the following resource allocations per node: Resource Allocation Unlike standard virtual routers like vSRX or modern
Using this specific, mature version of vQFX allows engineers to:
: The virtual FPC (Flexible PIC Concentrator) may not be online yet. Wait 2–3 minutes after the login prompt appears. The FPC can take time to load, but it will come online. The FPC can take time to load, but it will come online
By correctly deploying this image, you unlock the ability to simulate advanced EVPN-VXLAN data center fabrics on your laptop or server, providing a powerful lab environment for Juniper certification study or architecture validation.
: Because the vQFX emulates hardware ASICs in software, it is highly CPU-intensive. CPU Spikes
Running a full vQFX node (RE + PFE) requires significant resources.
