How to modify a virtual machine
Introduction
This section shows you how to use Ansible to modify an existing virtual machine.
Scenario requirements
You’ve already followed How to create a Virtual Machine and created a VM.
How to add a CDROM drive to a virtual machine
In this example, we use the vcenter_vm_hardware_*
modules to add a new CDROM to an existing VM.
Add a new SATA adapter
First we create a new SATA adapter. We specify the pci_slot_number
. This way if we run the task again it won’t do anything if there is already an adapter there.
- name: Create a SATA adapter at PCI slot 34
vmware.vmware_rest.vcenter_vm_hardware_adapter_sata:
vm: '{{ test_vm1_info.id }}'
pci_slot_number: 34
register: _sata_adapter_result_1
Result
{
"value": {
"bus": 0,
"pci_slot_number": 34,
"label": "SATA controller 0",
"type": "AHCI"
},
"id": "15000",
"changed": true
}
Add a CDROM drive
Now we can create the CDROM drive:
- name: Attach an ISO image to a guest VM
vmware.vmware_rest.vcenter_vm_hardware_cdrom:
vm: '{{ test_vm1_info.id }}'
type: SATA
sata:
bus: 0
unit: 2
start_connected: true
backing:
iso_file: '[ro_datastore] fedora.iso'
type: ISO_FILE
register: _result
How to attach a VM to a network
Attach a new NIC
Here we attach the VM to the network (through the portgroup). We specify a pci_slot_number
for the same reason.
The second task adjusts the NIC configuration.
- name: Attach a VM to a dvswitch
vmware.vmware_rest.vcenter_vm_hardware_ethernet:
vm: '{{ test_vm1_info.id }}'
pci_slot_number: 4
backing:
type: DISTRIBUTED_PORTGROUP
network: "{{ my_portgroup_info.dvs_portgroup_info.dvswitch1[0].key }}"
start_connected: false
register: vm_hardware_ethernet_1
Result
{
"value": {
"start_connected": false,
"pci_slot_number": 4,
"backing": {
"connection_cookie": 2145337177,
"distributed_switch_uuid": "50 33 88 3a 8c 6e f9 02-7a fd c2 c0 2c cf f2 ac",
"distributed_port": "2",
"type": "DISTRIBUTED_PORTGROUP",
"network": "dvportgroup-1649"
},
"mac_address": "00:50:56:b3:49:5c",
"mac_type": "ASSIGNED",
"allow_guest_control": false,
"wake_on_lan_enabled": false,
"label": "Network adapter 1",
"state": "NOT_CONNECTED",
"type": "VMXNET3",
"upt_compatibility_enabled": false
},
"id": "4000",
"changed": true
}
Adjust the configuration of the NIC
- name: Turn the NIC's start_connected flag on
vmware.vmware_rest.vcenter_vm_hardware_ethernet:
nic: '{{ vm_hardware_ethernet_1.id }}'
start_connected: true
vm: '{{ test_vm1_info.id }}'
Increase the memory of the VM
We can also adjust the amount of memory that we dedicate to our VM.
- name: Increase the memory of a VM
vmware.vmware_rest.vcenter_vm_hardware_memory:
vm: '{{ test_vm1_info.id }}'
size_MiB: 1080
register: _result
Upgrade the hardware version of the VM
Here we use the vcenter_vm_hardware
module to upgrade the version of the hardware:
- name: Upgrade the VM hardware version
vmware.vmware_rest.vcenter_vm_hardware:
upgrade_policy: AFTER_CLEAN_SHUTDOWN
upgrade_version: VMX_13
vm: '{{ test_vm1_info.id }}'
register: _result
Adjust the number of CPUs of the VM
You can use vcenter_vm_hardware_cpu
for that:
- name: Dedicate one core to the VM
vmware.vmware_rest.vcenter_vm_hardware_cpu:
vm: '{{ test_vm1_info.id }}'
count: 1
register: _result
Remove a SATA controller
In this example, we remove the SATA controller of the PCI slot 34.
{
"changed": true
}
Attach a floppy drive
Here we attach a floppy drive to a VM.
- name: Add a floppy disk drive
vmware.vmware_rest.vcenter_vm_hardware_floppy:
vm: '{{ test_vm1_info.id }}'
allow_guest_control: true
register: my_floppy_drive
Attach a new disk
Here we attach a tiny disk to the VM. The capacity
is in bytes.
- name: Create a new disk
vmware.vmware_rest.vcenter_vm_hardware_disk:
vm: '{{ test_vm1_info.id }}'
type: SATA
new_vmdk:
capacity: 320000
register: my_new_disk
