              Hi All!
I’m running Ansible v2.3, and want to know if it’s possible to create virtual machines with NIC’s, without specifying a MAC address.
While it’s listed as optional in the docs (http://docs.ansible.com/ansible/vmware_guest_module.html ), the playbook fails unless a mac entry is created.
Version Info: 
`
ansible 2.3.0.0
config file = /etc/ansible/ansible.cfg
configured module search path = Default w/o overrides
python version = 2.7.5 (default, Nov 6 2016, 00:28:07) [GCC 4.8.5 20150623 (Red Hat 4.8.5-11)]
Example playbook: 
`
             
            
              
            
           
          
            
            
              Bit of a wild guess this, but just wondering if the issue is indentation?
disk:- size_gb: "{{ disk_size }}"type: thindatastore: "{{ datastore }}"hardware:memory_mb: "{{ memory }}"num_cpus: "{{ cpucount }}"networks:- name: VM Network
might need to be
disk:- size_gb: "{{ disk_size }}"type: thindatastore: "{{ datastore }}"hardware:memory_mb: "{{ memory }}"num_cpus: "{{ cpucount }}"networks:- name: VM Network

              No luck there - changing the indentation yields the same error.

              Found the issue!
The create_nic function within the vmware_guest module sets the nic’s address type as ‘assigned’, which requires you to supply a MAC address.
I’ve submitted a patch to fix this: https://github.com/ansible/ansible/pull/24138
