While it requires significant RAM (usually 2GB to 4GB per RE), it scales better than trying to run full physical hardware simulations. Key Requirements for Running vQFX202R110

The RE image must be renamed to hda.qcow2 .

This is the second VM. It runs a specialized, lightweight forwarding plane. Its role is to simulate the ASIC microcode. You usually need a separate PFE image (e.g., vqfx-20.2R1-2019010209-pfe-qemu.qcow ) .
