Ansible - bigip_software_install on a vCMP ?

Hello,

With ansible, is it possible to use the module bigip_software_install on a vCMP ? I can use it on the chassis but I keep getting errors on the vCMP.

The error I keep getting :

The full traceback is:
Traceback (most recent call last):

My equipment :

BIG-IP 7800
with two vCMP
everything in version 12.1.3.0.0.378

I want to upgrade to 12.1.4-0.0.8.

If the module bigip_software_install doesn't work on a vCMP, i think i'll try the bigip_command to upgrade.
