The is the specific QEMU-formatted disk image for the Routing Engine (RE) of Juniper’s vQFX 20.2R1.10 virtual switch. In a virtualized environment, this image acts as the "brain" of the switch, handling the control plane and management, while a separate Packet Forwarding Engine (PFE) image handles the data plane.
Juniper networks' architecture separates the brain of the switch from its muscles. To emulate this on an ordinary computer, the system splits the software into two distinct virtual devices: vQFX expects virtio-blk , not sata
