The full phrase vqfx202r110reqemuqcow2 top typically emerges from a production environment where an administrator has just launched a vQFX instance and wants to verify its resource usage (CPU, memory, I/O) using the top utility. vqfx202r110reqemuqcow2 top

To understand the file name, we have to break down its components:

Handled by a separate companion image (often a cosmic/PFE QCOW2 image). It simulates the hardware ASIC, switching matrix, and physical port packet processing.

Handles the data plane. It requires a separate PFE-specific image. 1. Preparation in EVE-NG

Processes control plane traffic (OSPF, BGP, SSH). This is the image you have.

Powered by a companion image (typically named vqfx-20.2R1-2019010209-pfe-qemu.qcow or similar). This VM emulates the switching ASIC, handling packet forwarding, ACLs, and interface line-rate behaviors.

The search string refers to a highly targeted, specific file format and image version utilized by network engineers: the Juniper vQFX Virtual Routing Engine ( re ) image , built for the QEMU/KVM hypervisor , package version 20.2R1.10 , formatted as a QCOW2 (QEMU Copy-On-Write) disk volume.

Run the EVE-NG wrapper script to apply correct read/write permissions to the newly added file. /opt/unetlab/wrappers/unl_wrapper -a fixpermissions Use code with caution. Step-by-Step GNS3 Setup

If you prioritize I/O performance over snapshot features, convert the image to raw:

QCOW2 (QEMU Copy On Write), which is highly efficient, allowing for sparse file usage and snapshots.
