After building, you can define a juniper_vqfx kind in your topology file and deploy it with a single containerlab deploy command.
Unlike monolithic network virtual appliances, the virtual QFX platform splits its operations across two distinct virtual machines. To successfully stand up a switch, you must spin up both elements and stitch them together over a dedicated virtual link.
sudo mv ~/downloads/vqfx202r1-10.qcow2 /var/lib/libvirt/images/ sudo chown libvirt-qemu:libvirt-qemu /var/lib/libvirt/images/vqfx202r1-10.qcow2 vqfx202r110reqemuqcow2 exclusive
virsh start vqfx-spine-1 virsh attach-interface --type bridge --source br0
Apply the latest QEMU binaries on your host machine. Alternatively, configure the Junos system to enter an idle state when processing loops are clear by applying any available Juniper kernel optimization scripts meant for virtual environments. After building, you can define a juniper_vqfx kind
Never just close your emulator. Run request system power-off from the Junos CLI and wait for the VM to stop.
mkdir /opt/unetlab/addons/qemu/vqfxre-20.2R1.10 sudo mv ~/downloads/vqfx202r1-10
: Use qemu-img convert -O qcow2 -o preallocation=metadata to speed up cluster allocations.
The Junos 20.2R1.10 image can occasionally exhibit specific failures during initial boot or when connecting to the PFE data plane.
Move your vqfx202r110reqemuqcow2 file into that folder using an SFTP client and rename it to the default name EVE-NG expects for hard disks ( virtioa.qcow2 ).
