When requesting multiple VMs through the API, a priority can be assigned. The lower the priority integer, the higher the urgency:

# Request a VM with the highest priority (default priority is 1000)
curl -X POST "http://anka.controller/api/v1/vm" -H "Content-Type: application/json" \
  -d '{"vmid": "6b135004-0c89-43bb-b892-74796b8d266c", "count": 2, "priority": 1}'

{
  "status": "OK",
  "message": "",
  "body": [
    "c983c3bf-a0c0-43dc-54dc-2fd9f7d62fce",
    "e74dfc0e-dc94-4ca2-575e-3219ac08ffa2"
  ]
}
