    node:
      - {"src": "leaf01", "src_label": "e0/3", "dst": "leaf02", "dst_label": "e0/3"}

Additional context
It works fine using any qemu devices, also its posible to add iol devices using CLI and works fine: Ex: eve-ng node create --name testnode--nde-type iol --template iol --image i86bi_LinuxL3-AdvEnterpriseK9-M2_157_3_May_2018.bin
