2020.04.22 – Juniper vQFX installation into EVE-PRO

Inspiration in EVE guid: https://www.eve-ng.net/index.php/documentation/howtos/howto-add-juniper-vqfx/

Note in 2021.05.14: I used vQFX in my labs and I had many problems. PING does not work! At the version 20.2 also does not work ping. Now I install and try to use vQFX 20.3. I will come back here to say my result!!

Note in 2021.05.16: I tried all vQFX versions that I find to download from Juniper. No one work for me. Support EVE-PRO helped me with a vQFX 18.4 and was OK to ping between 2 different vQFX switches.

vQFX 18.4 contains different applications .qcow2 or .qcow or .img to download from Juniper. I used 2 Application Media 18.4R2-S2 but maybe EVE-PRO helped me with application, one or both, from Application Package.

To find a version it works, you have to try many possibility!!

Original article

Step 1

Use your Juniper access for login and download images.

  • PFE downloaded image file: 
    • For version 17.4R1: cosim_20180212.qcow2
    • For version 19.4R1: vqfx-19.4R1-2019010209-pfe-qemu.qcow
  • RE downloaded file: 
    • For version 17.4R1: jinstall-vqfx-10-f-17.4R1.16.img
    • For version 19.4R1: vqfx-19.4R1.10-re-qemu.qcow2

Step 2

SSH CLI to your EVE as root and create two new image directories in: /opt/unetlab/addos/qemu/

  • For version 17.4R1:
mkdir /opt/unetlab/addons/qemu/vqfxpfe-10K-F-17.4R1.16
mkdir /opt/unetlab/addons/qemu/vqfxre-10K-F-17.4R1.16
  • For version 19.4R1:
mkdir /opt/unetlab/addons/qemu/vqfxpfe-10K-F-19.4R1 
mkdir /opt/unetlab/addons/qemu/vqfxre-10K-F-19.4R1

Step 3

Upload the downloaded images to the EVE newly created directories using FileZilla (or WinSCP).

  • For version 17.4R1:
  1. cosim_20180212.qcow2 to /opt/unetlab/addons/qemu/vqfxpfe-10K-F-17.4R1.16/cosim_20180212.qcow2
  2. jinstall-vqfx-10-f-17.4R1.16.img  to /opt/unetlab/addons/qemu/vqfxre-10K-F-17.4R1.16/jinstall-vqfx-10-f-17.4R1.16.img
  • For version 19.4R1:
  1. vqfx-19.4R1-2019010209-pfe-qemu.qcow to /opt/unetlab/addons/qemu/vqfxpfe-10K-F-19.4R1
  2. vqfx-19.4R1.10-re-qemu.qcow2  to /opt/unetlab/addons/qemu/vqfxre-10K-F-19.4R1.1

Step 4

Rename original filenames to EVE format Use commands from EVE CLI

  • For version 17.4R1:
mv /opt/unetlab/addons/qemu/vqfxpfe-10K-F-17.4R1.16/cosim_20180212.qcow2 /opt/unetlab/addons/qemu/vqfxpfe-10K-F-17.4R1.16/hda.qcow2
mv /opt/unetlab/addons/qemu/vqfxre-10K-F-17.4R1.16/jinstall-vqfx-10-f-17.4R1.16.img /opt/unetlab/addons/qemu/vqfxre-10K-F-17.4R1.16/hda.qcow2
  • For version 19.4R1:
root@eve-ng:/opt/unetlab/addons/qemu/vqfxpfe-10K-F-19.4R1# mv vqfx-19.4R1-2019010209-pfe-qemu.qcow hda.qcow2
root@eve-ng:/opt/unetlab/addons/qemu/vqfxre-10K-F-19.4R1# mv vqfx-19.4R1.10-re-qemu.qcow2 hda.qcow2
root@eve-ng:/opt/unetlab/addons/qemu# ls 
vqfxpfe-10K-F-19.4R1     vqfxre-10K-F-19.4R1
vqfxpfe-10k-F-17.4R1.16  vqfxre-10k-F-17.4R1.16

root@eve-ng:/opt/unetlab/addons/qemu# ls vqfxpfe-10K-F-19.4R1
root@eve-ng:/opt/unetlab/addons/qemu# ls vqfxre-10K-F-19.4R1.1

Step 5

Fix permissions

/opt/unetlab/wrappers/unl_wrapper -a fixpermissions

Step 6.

Create new lab, add PFE and RE nodes on topology. Interconnect pair RE-PFE with em1 interface.


  • Before Power ON EVE-PRO or, if EVE-PRO is on, before Power ON vQFX, run a command in EVE-PRO:
root@eve-ng:~# echo "10000" > /sys/module/kvm/parameters/halt_poll_ns

Step 7.

Power On PFE and RE.

Login in RE, user and password:

  • On version 19.4R1.1: root/Juniper
  • On version 17.4R1,4: root/no password

Step 8. Use Terminal for configuration

To connect and configure vQFX from Terminal in MacBook Pro:

  • In EVE-NG create a new Network
    • Type : Cloud1 with name Management (Cloud1)
    • Connect vQFX-RE with Management (Cloud1) using em0/fxp0 interface

Clod1 in mine VMware Fusion means:

Lab cloud name: Cloud1EVE interface: pnet1VMware Fusion VM: Network Adapter 2Bare HW Server:
answer VNET_91_DISPLAY_NAME JunOS-fxp0
Bare HW Server:
Bare HW Server:
  • In vQFX-RE configure fxp0 interface
{master:0}[edit interfaces em0]
root@vqfx-re# show 
unit 0 {
    family inet {
  • Connect to vQFX-RE from Terminal

NOTE: If you can not connect it seams there are some interfaces problem!!

1. Go back in EVE-PRO, open vqfx-re then continue as shown

root@vqfx-re:RE:0% cli

root@vqfx-re > show interface terms 
Interface               Admin      Link    Proto    Local
 --- missing xe- interface ---
???                      down       up 

2. If you see Admin down part, no meter what interface name is, then go to next step:

root@vqfx-re > exit

root@vqfx-re:RE:0% reboot

To solve this problem is mandatory to reboot this way!!!

3. When reboot finished:

root@vqfx-re:RE:0% cli

root@vqfx-re > show interface terms
