Understanding and Deploying the Juniper vQFX Virtual Switch (vqfx202r110reqemuqcow2)
: Runs the Control Plane (Junos OS) 5.2.3.
: If you cannot see interfaces (XE-0/0/0, etc.) in the CLI, the link between the re and pfe QEMU instances is likely wrong. Ensure em0 is used 5.2.1. vqfx202r110reqemuqcow2
Deploying the vqfx-20.2R1.10-re-qemu.qcow2 image via the command line requires creating a QEMU instance and binding the appropriate virtual interfaces. Step 1: Create a Copy of the Base Image
This often indicates insufficient resources or incorrect image format. Ensure you have allocated at least 1024 MB RAM to the RE and that your hypervisor supports the required QEMU version (2.9.0 or newer is recommended).

Once your vQFX boots (which can take 5-10 minutes for the first start), it's time to log in and verify the operation. There is a documented issue where some versions
Right-click and add a node (select the 20.2R1.10 version). Right-click and add a Juniper vQFX PFE node.
The consists of two separate virtual machines that must work together:
To verify that your RE image has successfully connected to your PFE image and that your operational data ports are active, run the following command from operational mode: root> show interfaces terse | match xe- Use code with caution.
Connect em1 (or the designated internal control interface) of the RE node to em1 of the PFE node. This establishes the internal connection between the brain and the muscle of the virtual switch. Can’t copy the link right now
: The file extension and disk image format. QCOW2 (QEMU Copy On Write) is the standard storage format for QEMU/KVM. It is highly efficient because it grows dynamically, taking up physical disk space only as data is written to the virtual drive. The Dual-VM Architecture of vQFX
: This is the image represented by vqfx-20.2R1.10-re-qemu.qcow2 . It runs the Junos control plane, managing configurations, routing protocols (like BGP, OSPF, and EVPN), user authentication, and system management.
: This is the crown jewel. The QCOW2 (QEMU Copy On Write version 2) format is the industry standard for QEMU-based virtualization. It is the file format of this image. Its key features make it indispensable for lab use:
