Vqfx202r110reqemuqcow2 [hot]
: To fully simulate a switch, the vQFX typically requires two separate virtual machines: the Routing Engine (RE) Packet Forwarding Engine (PFE) Connectivity
: The standard QEMU Copy-On-Write disk storage format. It optimizes disk space by dynamically allocating storage rather than inflating the full provisioned file size up front. 2. The Twin-VM Architecture: RE vs. PFE
: Stands for Routing Engine . The vQFX architecture is split into two distinct virtual machines: the Routing Engine (RE), which runs the control plane (OS, routing protocols, management), and the Forwarding Engine (PFE), which handles the data plane. This specific file is the RE image.

New images often come with a large number of pre-configured "XC" interfaces that can clutter your setup. Use the following command in configuration mode to clear them: wildcard delete interfaces xe-* ⚠️ Known Issues & Tips download for vQFX 20.2 is actually 19.4 | Data Center
The RE and PFE communicate over an internal virtual bridge network. Without the PFE, the RE will boot and allow you to configure Junos, but the network interfaces will remain down or fail to pass traffic. System Requirements for Deployment : To fully simulate a switch, the vQFX

: Built natively for the Quick Emulator (QEMU) hypervisor.
: Ensure KVM acceleration ( -enable-kvm ) is active on your host system. Junos requires hardware acceleration to execute nested kernel instructions efficiently. The Twin-VM Architecture: RE vs
This is the vqfx202r110reqemuqcow2 file. It handles SSH connections, configuration management, routing protocols (like BGP, OSPF, and EVPN), and API interactions.
Handled by vqfx-20.2R1.10-re-qemu.qcow2 . This acts as the brain of the switch. It processes control plane traffic, hosts the Junos CLI, calculates routing tables, and manages routing protocols (such as OSPF, BGP, and EVPN).
Deploying the vqfx202r110reqemuqcow2 image unlocks data center feature validation directly from a laptop, local server, or cloud environment.
⚠️ : vQFX requires model=virtio for data plane interfaces. Use bridge=br0 if you have a physical bridge.
