Containerlab (a popular tool for containerized network topologies) supports the Juniper vQFX kind. You can define complex spine-leaf fabrics in a YAML file and let containerlab handle the QEMU boot process. As noted in the community, when using the public image, rename the downloaded qcow2 to match the version expected by the tool to avoid boot mismatches .

Deploying high-performance data center topologies requires robust virtualized environments. serves as the Routing Engine (RE) image for Juniper Networks' vQFX virtual switch . This specific virtual disk file allows network engineers to simulate a physical QFX10000 series switch within Kernel-based Virtual Machine (KVM) and QEMU-backed emulation software like EVE-NG or GNS3 .
