Adding Arista vEOS images to UnetLab

Leave a reply

Arista provides a number of VM type images that you can use. The one with the software forwarding plane is vEOS-lab. This image has all the control plane features of standard EOS from Arista, with a software dataplane – the downside to this is that features that rely on the hardware e.g. NAT aren’t available.

There are two files required to get a working vEOS switch. The vmdk file and the Aboot ISO. To create a working vEOS on 4.17.5M we need:

  • vEOS-lab-4.17.5M.vmdk
  • Aboot-veos-serial-8.0.0.iso

To create an image that UnetLab will recognise the following steps should turn the trick

  1. Create the directory for the version in question
  2. Copy the two files in there
  3. Convert the vEOS-lab-4.17.5M.vmdk to a qcow image
  4. Rename the Aboot ISO to cdrom.iso file
  5. All done – fire up your Lab and select Arista vEOS as the template
mkdir /opt/unetlab/addons/qemu/veos-4.17.4M/
/opt/qemu/bin/qemu-img convert -f vmdk -O qcow2 ./vEOS-4.17.5M.vmdk hda.qcow2
mv Aboot-veos-serial-8.0.0.iso /opt/unetlab/addons/qemu/veos-4.17.5M/cdrom.iso
rm ./vEOS-4.17.5M.vmdk
/opt/unetlab/wrappers/unl_wrapper -a fixpermissions
