A new virtual machine can be created with as few as the following attributes in JSON format:
{"usage": "Prod",
"os": "ubuntu64Guest",
"built_from": "os_install",
"client": "EIS",
"description": "Java web application.",
"folder": "group-v4122",
"networks": [{"network": "dvportgroup-95", "type": "e1000"}, {"network": "dvportgroup-92"}],
"disks": [40, 100],
"power_on": true
}
HTTPie
http POST "https://vss-api.eis.utoronto.ca/v2/vm" "Authorization: Bearer $TK" usage='Prod' os='ubuntu64Guest' built_from='os_install' client='EIS' description='Java web application.' folder='group-v4122' networks:='[{"network": "dvportgroup-95", "type": "e1000"}, {"network": "dvportgroup-92"}]' disks:='[40, 20]' power_on:=true
CURL
curl -H "Content-Type: application/json" -H "Authorization: Bearer $TK" -X POST "https://vss-api.eis.utoronto.ca/v2/vm" -d '{"usage": "Prod", "os": "ubuntu64Guest", "built_from": "os_install", "client": "EIS", "description": "Java web application.", "folder": "group-v4122", "networks": [{"network": "dvportgroup-95", "type": "e1000"}, {"network": "dvportgroup-92"}], "disks": [40, 100], "power_on": true}'
If the request was successfully submitted and all parameters were accepted, the following Response Status, Headers and body will be received:
HTTP/1.0 202 ACCEPTED Allow: HEAD, POST, OPTIONS, GET Content-Length: 364 Content-Type: application/json Date: Tue, 26 Apr 2016 18:24:23 GMT Location: https://vss-api.eis.utoronto.ca/v2/request/task/fa276e28-a876-477a-ab40-0d2d84df9234 X-RateLimit-Limit: 7200 X-RateLimit-Remaining: 7190 X-RateLimit-Reset: 1461697200
Note that you will receive as well additional Hypermedia links contained in the _links attribute. Request object is the new virtual machine creation request which stores all parameters previously submitted and Task, is the unique task in charged of processing your request. Request and Task are both related, in terms of status, errors and warnings. Request will store any status or errors caught by the task, also it will pass the recently created VM Uuid.
Task
Request processing is almost instantaneous, however you could check the task progress by making a HTTP GET request to any given /v2/request/task/<task_id> endpoint.
RequestÂ
Checking the overall status of the request and also the resulting Uuid can be done by making a HTTP GET request to /v2/request/new/8 endpoint:
Multiple Virtual Machines
To create multiple Virtual Machines, send a POST request to /v2/vm. Creating multiple VMs is quite similar to creating a single VM, but instead of sending name as a string, send names as an array and select the right built process, either clone or template. The following request body is used to deploy three VM from a VM template:
{"": "EIS",
"built_from": "template",
"description": "Ubuntu cluster",
"os": "ubuntu64Guest",
"folder": "group-v4122",
"source_template": "50123c4c-c810-5c0f-6203-eac67f0cb7e8",
"names": ["Ubuntu1",
"Ubuntu2",
"Ubuntu3"],
"networks": [
{"network": "dvportgroup-95", "type": "e1000"},
{"network": "dvportgroup-92", "type": "vmxnet3"}
],
"disks": [40, 100]}
The main difference between selecting clone or template as built process is that a source VM Template can deploy multiple instances concurrently, whereas a VM Clone can only be deployed concurrently when the source Virtual Machine is powered off. If VM is powered On, it can only be cloned one at a time.
HTTPie
http POST "https://vss-api.eis.utoronto.ca/v2/vm" "Authorization: Bearer $TK" os='ubuntu64Guest' built_from='template' client='EIS' description='Ubuntu cluster' folder='group-v4122' networks:='[{"network": "dvportgroup-95", "type": "e1000"}, {"network": "dvportgroup-92"}]' disks:='[40, 100]' names:='["Ubuntu1", "Ubuntu2", "Ubuntu3"]' source_template=50123c4c-c810-5c0f-6203-eac67f0cb7e8

The main difference between single and multiple vm creation/deployment is the number of requests and tasks returned by the API. In this case, since we required three VMs, we get the same number of requests and tasks as a result of the POST request, which can be queried individually to verify its progress or result.
Task
Request processing is almost instantaneous, however you could check the task progress by making a HTTP GET request to any given /v2/request/task/<task_id> endpoint.
Requests
Checking the overall status of the requests and also the resulting Uuid can be done by making a HTTP GET request to /v2/request/new/26 - 28 endpoint:
List
Virtual machines
In order to list all your Virtual Machines you should make a HTTP GET request to the endpoint /v2/vm:
The following examples use HTTPie and CURL to request ALL Virtual Machine managed by given user without filters:
http GET "https://vss-api.eis.utoronto.ca/v2/vm" "Authorization: Bearer $TK" curl -H "Authorization: Bearer $TK" -X GET "https://vss-api.eis.utoronto.ca/v2/vm"
HTTP response data would look something like:
Included attributes are described in the following table:
| Name | Type | Description |
|---|---|---|
| uuid | string | 128-bit UUID of a virtual machine, represented as a hexademical string. This identifier is used by VirtualCenter to uniquely identify all virtual machine instances, including those that may share the same SMBIOS UUID. |
| moref | string | Managed object reference of the vm |
| name | string | Virtual Machine name including VSS prefix. |
| guest_full_name | string | The full name of the guest operating system for the virtual machine. For example: Windows 2000 Professional. |
| guest_id | string | The guest operating system identifier. |
| ip_address | string | Primary IP address assigned to the guest operating system, if known. |
| hostname | string | Guest hostname. Provided only when VMware Tools is running. |
memoryGB | integer | Memory size of the virtual machine, in Gigabytes. |
cpu_count | integer | Number of processors in the virtual machine. |

| tools_running_status | string | VMware Tools running status. |
| tools_version | string | VMware Tools version. |
| tools_version_status | string | VMware Tools version status. |
| version | string | Virtual hardware version. |
Paging
All requests to the /vm URL are paginated. The response body includes a 'meta.pages' key with everything to navigate through the results, for instance:
| Key | Description |
|---|---|
| first_url | Contain the URLs to navigate through results. |
| last_url | |
| prev_url | |
| next_url | |
| page | Current page |
| pages | Total number of pages |
| per_page | Results per page. Maximum 250; Default 10. |
| total | Total number of results |
Results per page can be set by including the parameter in the URL query, so we can get the desired number of elements per page, for example:
http GET "https://vss-api.eis.utoronto.ca/v2/vm?per_page=200" "Authorization: Bearer $TK" curl -H "Authorization: Bearer $TK" -X GET "https://vss-api.eis.utoronto.ca/v2/vm?per_page=1500"
Sorting
The resource provides also attribute sorting by adding the sort parameter in the URL query string in the following format:
sort=<field_name>,<asc|desc>
For example:
http GET "https://vss-api.eis.utoronto.ca/v2/vm?sort=name,desc" "Authorization: Bearer $TK" http GET "https://vss-api.eis.utoronto.ca/v2/vm?sort=uuid,asc" "Authorization: Bearer $TK"
Filtering
Virtual Machines can be filtered by adding the filter argument to the query string in the following format:
filter=<field_name>,<operator>,<value>
Operators can be:
| Operator | Description |
|---|---|
| eq | Equals |
| ne | Not equal |
| lt | Lower than |
| le | Lower equal |
| gt | Greater than |
| ge | Greater equal |
| like | Matching pattern |
| in | Match value in many items separated by commas |
Filter Virtual Machine resource by any of the following
| Attribute | Filter |
|---|---|
| name | name |
| ipAddress | ip_address |
| hostname | hostname |
| powerState | power_state |
| cpuCount | cpu_count |
| overallStatus | overall_status |
| toolsVersion | tools_version |
| toolsVersionStatus | tools_version_status |
| version | version |
The following examples show how to implement a GET request with the first three parameters shown below. The result is similar to the previous section.
http GET "https://vss-api.eis.utoronto.ca/v2/vm?filter=name,like,%Test%" "Authorization: Bearer $TK" http GET "https://vss-api.eis.utoronto.ca/v2/vm?filter=ip_address,eq,10.2.1.2" "Authorization: Bearer $TK" http GET "https://vss-api.eis.utoronto.ca/v2/vm?filter=hostname,like,wiki.eis.utoronto.ca" "Authorization: Bearer $TK"
Filtering by name can be done as follows:
http GET "https://vss-api.eis.utoronto.ca/v2/vm?filter=name,like,%Test%" "Authorization: Bearer $TK"
HTTP response data would look something like:
