If the image hangs at the GRUB bootloader or continually reboots during the kernel initialization phase, your CPU definition is likely incompatible. Ensure you are using -cpu host in raw QEMU, or ensure your nested virtualization flags are enabled on the physical host machine by running: cat /sys/module/kvm_intel/parameters/nested Use code with caution. It should return Y or 1 . 2. Interfaces (xe-0/0/0, etc.) are Missing Intel VT-x or AMD-V enabled in the BIOS/UEFI

Expect a 3–5 minute boot cycle. This is standard for Junos VM images. Resource Footprint: Requires a minimum of 2GB RAM (4GB recommended). Uses the QEMU/KVM hypervisor efficiently.

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.

This technical guide provides a comprehensive walkthrough for running the Juniper vQFX10000 virtual switch (Routing Engine image version vqfx202r110reqemuqcow2 ) within a QEMU/KVM environment. Network engineers frequently use this specific QEMU Copy-On-Write (qcow2) image to simulate Junos OS features in virtual labs like GNS3, EVE-NG, or raw Linux KVM hypervisors.
