Have you tried to install libvirt-python by using  pip install libvirt-python  on your server

In the command which you have given, you have not mentioned the vm type i.e, veos or ceos or vsonic or vcisco

Try with the following command:

cd /data/sonic-mgmt/ansible

./testbed-cli.sh -t vtestbed.yaml -m veos_vtb -k ceos add-topo vms-kvm-t0 password.txt

Replace "ceos" with the vm you prefer to use accordingly.
