RE downloaded file: jinstall-vqfx-10-f-17.4R1.16.img

Step 2

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

mkdir /opt/unetlab/addons/qemu/vqfxpfe-10K-F-17.4R1.16

mkdir /opt/unetlab/addons/qemu/vqfxre-10K-F-17.4R1.16

Step 3

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

cosim_20180212.qcow2 to  /opt/unetlab/addons/qemu/vqfxpfe-10K-F-17.4R1.16

jinstall-vqfx-10-f-17.4R1.16.img  /opt/unetlab/addons/qemu/vqfxre-10K-F-17.4R1.16
