Once the boot process completes, access the console and perform the initial setup:

This file is a Juniper virtual QFX switch running Junos OS 20.2R1.10, designed to run on a Linux KVM host using the QCOW2 disk format.

Indicates optimization for the Quick Emulator (QEMU) hypervisor layer. Vqfx-20.2r1.10-re-qemu.qcow2

: The QEMU Copy-On-Write disk image format, supporting dynamic storage allocation and snapshots. The Dual-VM Architecture

Essentially, this file is the "brain" of the virtual switch. To function, it must be paired with a Packet Forwarding Engine (PFE) image, usually designated as vqfx-20.2r1.10-pfe-qemu.qcow2 . Key Features of Juniper vQFX 20.2 Once the boot process completes, access the console

Verify your internal link cable configuration. In EVE-NG or GNS3, ensure the port designated as the internal link (typically interface index 1, labeled em1 or eth1 ) is directly connected between the RE and PFE VMs. Additionally, ensure the PFE VM is powered on and has finished booting. Issue 2: Extreme CPU Spike on the Host Machine

Increase the node RAM to 4 GB in the configuration settings. If running inside a nested VM, run egrep -c '(vmx|svm)' /proc/cpuinfo on your host CLI to confirm virtualization passes through correctly. 3. Extremely Slow Boot Times The Dual-VM Architecture Essentially, this file is the

If the RE starts in a "non-master" role, a common workaround is to use the command request virtual-chassis reactivate or reboot both the RE and PFE simultaneously. Guide: Importing Juniper vMX and vQFX into CML2.4
