After creating a VM in virt-manager (using “Import existing disk image”), manually edit the XML with virsh edit vqfx-re :
Understanding how these split-architecture components interact via QEMU is critical for network engineers building BGP EVPN/VXLAN data center topologies in non-production environments. Understanding the Split Architecture Architecture
Start by checking the file you have. The exact filename should resemble vqfx202r110re.qcow2 or vqfx-20.2R1.10-re-qemu.qcow2 . Run:
Tools like GNS3 , EVE-NG , or PNETLab use this image to create virtual topologies. Users must typically define a "node template" that specifies: RAM: Minimum 2GB (4GB recommended). CPUs: 1 or 2 vCPUs. vqfx202r110reqemuqcow2 work

When building high-fidelity data center simulations, staging EVPN-VXLAN fabrics, or validating automated Junos scripts, finding a reliable virtual switch image is critical. The Juniper vQFX10000
Before diving into the file specifics, it's helpful to understand what vQFX is. The vQFX is a virtualized version of the Juniper Networks QFX10000 series of high-performance data center switches. This free tool replicates the control and data plane features of its physical counterpart, though with limited software forwarding performance. It's an ideal platform for creating instant virtual labs for proof-of-concept testing, script development, configuration validation, network change simulation, and training purposes.
In a standard deployment, this specific Routing Engine image does not work alone; it must be paired with a corresponding Packet Forwarding Engine (PFE) image to simulate a complete, functional network switch. Run: Tools like GNS3 , EVE-NG , or
With more context, I'd be happy to help you craft a post that effectively communicates your message!
To function correctly, the vQFX requires two separate virtual machines working in tandem:
