[libvirt] Need help with running libvirt-test-api

Hi All, I am new to libvirt; to create a virtual machine using libvirt-test-API framework, I am starting with "repos/domain/linux_domain.conf". Before starting the script, I downloaded Fedora-Server-DVD-aarch64-23.iso under /var/lib/libvirt/images, and changed the parameter "testfullimagepath" under global.cfg to reflect the path of iso image. On trying to run the script using python libvirt-test-api --casefile /home/fedora/libvirt-test-API/cases/linux_domain.conf -l 1 I am getting below error message. Please let me know how to resolve this.
