issues w.r.t chromeos test image as ansible host

[hara acharya]

Hi All,

I am trying to add a chromeOS test image based DUT to ansible inventory but not able to run any script on it using ansible.
But when changed to network OS  in hosts config ping works fine. But running a bash script doesn't work. I have also tried changing ansible.cfg file to reflect remote_temp to /tmp which has right permission and remote_user as root but no help.

Below is what I have tried so far. Can anybody help ?

hosts file config:
[duts]
172.25.235.142 ansible_password=test0000 ansible_user=root

Running a playbook:
# ansible-playbook remote_script_dut.yml
