How to change vmware network adapter with ansible - ansible

Question

Im using ansible 2.9.2, i need to replace network adapter on vmware specific vm.
In my vcenter vm settings i see :
Networks: Vlan_12
My playbook doesnt see that network name.
tasks:
- name: Changing network adapter
vmware_guest_network:
datacenter: "{{ datacenter"}}
hostname: "{{ vcenter_server }}"
username: "{{ vcenter_user }}"
password: "{{ vcenter_pass }}"
folder: "{{ folder }}"
cluster: "{{ cluster }}"
validate_certs: no
name: test
networks:
- name: "Vlan_12"
vlan: "Vlan_12"
connected: false
state: absent
register: output
I get this error:
fatal: [localhost]: FAILED! => {"changed": false, "msg": "Network 'Vlan_12' does not exist."}
Im trying to replace vlan_12 with another network adapter named Vlan_13, so i tried first to delete the exsisting network adapter. in ansible docs they have a very limited examples.
Thanks.

Answer 1

You dont have to poweroff the machine while addin/removing networks.
You can remove/add nic on the fly, well at least on linux vm's not sure about Win vm's.

Changing networks live works just fine. All you need is state: present, the label of your current interface (almost certainly 'Network adapter 1', which is the default for the first network interface), and the name of the port group that you'd like to connect to this interface.
Here's the playbook I've been using:
---
- hosts: localhost
gather_facts: no
tasks:
- name: migrate network
vmware_guest_network:
hostname: '{{ vcenter_hostname }}'
username: '{{ vcenter_username }}'
password: '{{ vcenter_password }}'
datacenter: '{{ datacenter }}'
validate_certs: False
name: '{{ vm_hostname }}'
gather_network_info: False
networks:
- state: present
label: "Network adapter 1"
name: '{{ new_net_name }}'
delegate_to: localhost

You need vmware specific machine to be powerdoff so you can change network adapter:
tasks:
- name: Changing network adapter
vmware_guest_network:
datacenter: "{{ datacenter"}}
hostname: "{{ vcenter_server }}"
username: "{{ vcenter_user }}"
password: "{{ vcenter_pass }}"
folder: "{{ folder }}"
cluster: "{{ cluster }}"
validate_certs: no
name: test
networks:
- name: "Vlan_12"
label: "Network adapter 1"
connected: False
state: absent
- label: "Network adapter 1"
state: new
connected: True
name: Vlan_13
This playbook deletes the present network adapter and the it adds the new adapter instead. i couldnt find a way to change. only delete and add.
