Some resources provide specialized URIs for actions. An API user performs a request on a resource's action, which launches a task specific to that resource.
A virtual machine contains functions to start, stop and shutdown. The API abstracts these function as actions specific to each virtual machine resource:
<vm id="6efc0cfa-8495-4a96-93e5-ee490328cf48" href="/rhevm-api/vms/6efc0cfa-8495-4a96-93e5-ee490328cf48">
<actions>
<link rel="start"
href="/rhevm-api/vms/6efc0cfa-8495-4a96-93e5-ee490328cf48/start"/>
<link rel="stop"
href="/rhevm-api/vms/6efc0cfa-8495-4a96-93e5-ee490328cf48/stop"/>
<link rel="shutdown"
href="/rhevm-api/vms/6efc0cfa-8495-4a96-93e5-ee490328cf48/shutdown"/>
...
</actions>
</vm>
