If you plan to stress-test using vqfx202r110reqemuqcow2 in a CI/CD pipeline, apply these:
A final command was whispered to the server— /opt/unetlab/wrappers/unl_wrapper -a fixpermissions —to ensure the files were accessible. Chapter 3: The Binding
Must connect directly to PFE Interface em1 . This is the internal control link between the brain (RE) and the muscle (PFE).
Usually a Management interface ( fxp0 ) and internal links to connect to the PFE. 3. Key Functionalities in Lab Environments When successfully deployed, the 20.2R1-10 version provides: vqfx202r110reqemuqcow2 work
serves as a popular candidate, offering a virtualized replica of physical QFX10000 high-performance hardware.
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:
For the node to function, the RE image must link cleanly to the PFE image using an internal virtual link. If they fail to communicate, the Junos CLI will boot up, but none of your physical-facing network interfaces will activate.

If the format is raw or vmdk, you will need to convert it:
Heavy. It generally requires 2048 MB to 4096 MB RAM and 2 vCPUs depending on the specific package.
; using the default Intel e1000 may prevent the PFE from being recognized. Interfaces Usually a Management interface ( fxp0 ) and
Eve-NG requires specific folder names to automatically apply the correct QEMU templates. Create the VRE directory: mkdir -p /opt/unetlab/addons/qemu/vqfxre-20.2R1.10/ Use code with caution. Move your renamed image into that directory: mv hda.qcow2 /opt/unetlab/addons/qemu/vqfxre-20.2R1.10/ Use code with caution.
If you are setting this up right now, let me know you are using (like EVE-NG, GNS3, or pure KVM). I can give you the exact network mapping topology or node templates needed to link your RE and PFE seamlessly. Share public link
