    According to the documentation:

    -- https://www.juniper.net/documentation/us/en/software/vjunos-router/vjunos-router-kvm/topics/vjunos-router-kvm-hw-requirements.html

    Note: vJunos-router is not supported on EVE-NG or any other deployments that launch vJunos from within a VM due to the constraints of deeply nested virtualization.

    Same story as with vJunosSwitch (although some people say it worked for them...haven't  tried  although as vJunosEVO was ok for mycase).

    In addition can't see any  EVE-NG template file for vJunos-router in github/gitlab.

    Hi,

    It supported on EVE-NG/PNETLAB. Now just waiting somebody from Juniper staff create the template like vJunos-Switch and vJunos-EVO. As i remember the previous template also create by Juniper Internal.

    Thanks

    I'll get one of the guys to spin a EVE-NG template for vJunos-router - its not much different from vJunos-switch as they are basically the same image modulo tweaks for chassis type.

    Hi @Art Stine ,

    Thanks for your action. My issue was vjunos-router can be spin up. and i'm just tweak template from vjunos-switch. But after finish loading then after 2-3 minutes it will hung. So i think it related to template in EVE-NG not exactly correct. I will wait the correct template from u.

    Thanks again.

    Can you share the serial console from your hung router instance?  And the QEMU cmd line that EVE generated. Thanks

    Hi @Stanley Liao ,

    May i know your vJunos-Router using connection same like vJunos-Evo? I means need PFE and RPIO like this url https://www.eve-ng.net/index.php/documentation/howtos/juniper-vjunos-evo-router/

    Thanks and appreciate your feedback

    No, no additional connection needed between RE and PFE.

    vJunos-router and vJunos-switch are the same base image/setup (both Junos), so their network and QEMU setup is similar. vJunosEvolved is a different beast - its a virtual PTX based on EVO.

    Hi all

      i assume then since i 've used the below options in the template for my AMD machine to boot the vJunosSwitch (not impressed as it's slow in my VM EVE-NG equipment instead of recommended bare metal ), the same options can be applied for the EVE-NG template for vJunosRouter  for AMD equipment:

    -smbios type=1,product=VM-VMX
    -cpu IvyBridge,ibpb=on,spec-ctrl=on,ssbd=on,virt-ssbd=on,svm=on,erms=off

    Hi,

    Now on vJunos-Router and vJunos-Switch pending on startup-config script feature. Like vMX-VCP and vQFX-RE it have startup-config script. Hopefully someone expert in .yml can do for vJunos-Router and vJunos-Switch.

    Thanks

     I have a question about vJunos-switch 25.2R1. I downloaded it to EVE and copied it to a vjunosswitch-25.2 directory as virtio.qcow2. It comes up, but tries to do a iPXE boot. After trying a number of times, it says "No bootable device." and just hangs. Any idea what I am doing wrong?

    Can ya check to make sure the image downloaded correctly? Verify the image with 'qemu-img':

    root@q-jlab-01a:/var/home/abstine/images# qemu-img info vJunos-switch-25.2R1.9.qcow2

    image: vJunos-switch-25.2R1.9.qcow2

    file format: qcow2

    virtual size: 31.8 GiB (34100740096 bytes)

    disk size: 3.74 GiB

        extended l2: false

    root@q-jlab-01a:/var/home/abstine/images# qemu-img check vJunos-switch-25.2R1.9.qcow2

    No errors were found on the image.

    I mis-named the image file. Virtio.qcow2 vs virtioa.qcow2
