Validating complex EVPN-VXLAN or BGP architectures. ⚠️ Key Considerations
Ensure your RE and PFE are properly linked via their internal "EM1" interfaces. Without that connection, the ge-0/0/x ports will never show as "up." Conclusion

: Because the vQFX emulates hardware ASICs in software, it is highly CPU-intensive. CPU Spikes
Place vqfx-20.2R1.10-re-qemu.qcow2 into your local GNS3/images/QEMU/ directory. Follow the GUI wizard to link the RE and PFE images.
: Performance often degrades significantly if CPU utilization exceeds 80%. 4. Basic Configuration Default Credentials (Note: case-sensitive). Initial Setup
Juniper's vQFX emulates physical QFX10000 data center hardware by decoupling the control plane from the data plane. You must always run two distinct virtual machines for every single switch in your topology: A: The vQFX control plane runs FreeBSD, and
A common mistake is failing to link the two VMs correctly. You must connect the interface of the RE directly to the em1 interface of the PFE. This creates the internal "backplane" that allows the switch to function. Troubleshooting the "19.4" Version Glitch Guide: Importing Juniper vMX and vQFX into CML2.4
This denotes the hypervisor format. These images are optimized for , which is the backbone of KVM virtualization on Linux servers.
When working with this specific release image, users often encounter two main issues:

When registering this specific QEMU virtual appliance inside your hypervisor, map your settings precisely to these hardware parameters: Juniper vQFX - - EVE-NG
Unlike monolithic virtual machines, the Juniper vQFX functions by splitting tasks across two separate virtualized environments:
Note: Due to the overhead of syncing the control and data planes, vQFX nodes can take . Do not panic if the PFE console output hangs on "Loading Linux.." indefinitely—this is expected behavior. Step-by-Step Deployment Across Multi-Platforms 1. Importing into GNS3
