VM power actions using the API

To perform a power action (except for reset) on a VM using the API:

Perform a GET request to obtain the VM object and find the VM state link
Create a virtualmachinestate object
Send a PUT request to the VM state link

The VM state link is a link in the VM object with the "rel" attribute set to state. The "title" attribute contains the current state. You can send a PUT request of a virtualmachine state object to the link (in the "href" attribute) to change the power state of the VM.

    {
      "title": "ON",
      "rel": "state",
      "type": "application/vnd.abiquo.virtualmachinestate+json",
      "href": "https://nardo40.bcn.abiquo.com:443/api/cloud/virtualdatacenters/2486/virtualappliances/2990/virtualmachines/19454/state"
    },

Here are some examples of virtualmachinestate objects and notes about changing VM states

Hard power off
```
{"state": "OFF"}
```
When you perform a power off via API, the response will include a link where you can monitor the progress of this operation. For an example of a hard power off, see https://wiki.abiquo.com/api/latest/VirtualMachinesResource.html#change-the-state-of-a-virtual-machine

Graceful shutdown

{"state": "OFF", "gracefulShutdown": true}

To perform a graceful shutdown, your VM will need to have guest extensions installed on it. After an operation completes, you can view the status of the task by going to the link in the accepted request link of the response. In this case, the graceful shutdown was successful.

curl -X PUT 'https://nardo40.bcn.abiquo.com:443/api/cloud/virtualdatacenters/2486/virtualappliances/2990/virtualmachines/19454/state' \

Power on
```
{"state": "ON"}
```
Pause
```
{"state": "PAUSED"}
```
Azure power off and deallocate
Azure has two power off states - powered off and deallocated.
- To power off a VM in Azure via the Abiquo API, use the graceful shutdown
- To deallocate a VM in Azure via the Abiquo API, use the hard power off
  - The deallocated VM will have a "deallocated" attribute that is set to "true".

To reset a VM using the API, use a POST request to the reset action link. If you are using a test environment, you may wish to add the --insecure option.
