I am writing a script where I deploy and configure VM's on a vSphere environment.

After the deployment I want to gather the IP's of the VM's for DNS registration.
Facts can be gathered for 2 or more VM's at the same time.
But how do I then use the gathered data to output a VM name with IP address?

For a single VM this works to get the IP, but when used with 2 VM's the variable is undefinied:

- debug:
 var: vm_guest_facts.instance.ipv4

Maybe my approach is wrong, but I am not really sure how else to do it.

- name: Gather facts from recently deployed VM's

 vmware_guest_facts:
 validate_certs: False
 hostname: " vcenter_hostname "
 username: " vcenter_user "
 password: " vcenter_pass "
 datacenter: " datacenter "
 name: " item.key "
 register: vm_guest_facts
 with_dict: " vmdetails "

- debug:
 var: vm_guest_facts

Results (the hostname and folder is Terraform, but this example only uses Ansible):

You might want to use json_query like this. Here, I am gathering facts from vmware_guest_facts and registering output in no_vm_result. Then, using this no_vm_result with json_query to iterate over all results and grabbing ipv4 which can be used to do anything. This is pretty straight forward thing.
