If the vQFX202R110-reqemuqcow2 is not working as expected, consider these common pitfalls:
The most critical barrier to making vqfx-20.2R1.10-re-qemu.qcow2 work is the assumption that it can run as a standalone virtual machine. Unlike simple virtual appliances, the vQFX mimics physical data center switches by dividing operations into two distinct entities: It runs Junos OS and handles the control
