Provision VM on a prefered ESXi Host with vmware_guest

[xenlo]

SUMMARY

According to the documentation, esxi_hostname attribute define on which ESXi host the virtual machine will run. But actually it doesn't behave like that.

As far as I use the vmware_guest against the vcenter I din't found a way to define a prefered ESXi host where my VM have to run on.

STEPS TO REPRODUCE

A simple loop task which create VMs with a prefered host as esxi_hostname attribut.

Here is an sample:

---
# Deploy some VMS

- name: Provisions VM hosts
  hosts: vcenter
  gather_facts: no

  vars:
    domain_name: "my_domain.net"
    vcenter_sso_pass: "{{ ansible_ssh_pass }}"
    datacenter_name: "my_little_DC"
    datastore_name: "my_vmfs_01"

    vm_list:
      - name: little-vm-1-01
        pref_node: node01
      - name: little-vm-1-02
        pref_node: node01
      - name: little-vm-1-03
        pref_node: node01
      - name: little-vm-2-02
        pref_node: node02
      - name: little-vm-2-01
        pref_node: node02
      - name: little-vm-3-01
        pref_node: node03
      - name: little-vm-3-02
        pref_node: node03
      - name: little-vm-3-03
        pref_node: node03
      - name: little-vm-3-04
        pref_node: node03
      - name: little-vm-3-05
        pref_node: node03

  tasks:
    - name: Provision VM
      vmware_guest:
        hostname: "{{ ansible_host }}"
        esxi_hostname: "{{ vm.pref_node }}.{{ domain_name }}"
        username: "Administrator@{{ domain_name }}"
        password: "{{ vcenter_sso_pass }}"
        validate_certs: no
        name: "{{ vm.name }}.{{ domain_name }}"
        state: poweredoff
        folder: "/"
        datacenter: "{{ datacenter_name }}"
        guest_id: "debian9_64Guest"
        hardware:
          num_cpus: 1
          memory_mb: 1024
        disk:
          - size_gb: 2
            type: thin
            datastore: "{{ datastore_name }}"
      loop: "{{ vm_list }}"
      loop_control:
        loop_var: vm
      delegate_to: localhost

EXPECTED RESULTS

The VMs are provisioned on there prefered node.

ACTUAL RESULTS

The VMs are created but on random ESXi hosts.

I had some investigations with @goneri already.

He created a PR #357 to test some changes (having the set of self.relospec.host independent if we use template or not).

And from my side I tried to force some RelocateVM_Task(…) after the CreateVM_Task(…) but without any success.
