According to Unetlab, Unetlab support the following version vMX:

14.1R1.10-domestic and 14.1R4.8-domestic

I can get the 14.1R1.10 easily from Internet. However, I can’t find a packaged 14.1R4.8 image for Unetlab. I went to Unetlab and ask for help. Unfortunately, nobody responded me. As I need to use the newer version for my eVPN lab (eVPN HA), I had to try my own best to get one.

I downloaded the 14.1R4.8 doemestic img file from Internet: jinstall-vmx-14.1R4.8-domestic.img

Interestingly, I used CLI qemu-img and found that the Juniper image file is qcow2 format! 

[root@localhost tmp]# qemu-img info jinstall-vmx-14.1R4.8-domestic.img | grep file.format
file format: qcow2

Like adding a normal image, I created a new folder /opt/unetlab/addons/qemu/vmx-14.1R4.8. Then uploaded the file “jinstall-vmx-14.1R4.8-domestic.img” to this newly created folder and renamed the files as “hda.qcow2”.

Till now, in the Unetlabe GUI, I am able to select this new Junos version for my vMX. Although I can power on this new version vMX, I still can’t really use it for my eVPN lab. The reason is:

Since 14.1R4, Juniper vMX will try to connect to a remote PFE, which means a different virtual machine as PFE. To change this default behaviour and use local PFE, I need to add a new line

vm_local_rpio=”1″  to /boot/loader.conf and save the file. The change need reboot to take effect. After reboot, I am able to use this new Juniper vMX in my eVPN lab.
