Instance Method Details

#add(data_center, opts = {}) ⇒ DataCenter

Creates a new data center.

Creation of a new data center requires the name and local elements. For example, to create a data center named mydc that uses shared storage (NFS, iSCSI or fibre channel) send a request like this:

POST /ovirt-engine/api/datacenters HTTP/1.1

With a request body like this:

<data_center>
  <name>mydc</name>
  <local>false</local>
</data_center>

Parameters:

• data_center (DataCenter) —

  The data center that is being added.

• opts (Hash) (defaults to: {}) —

  Additional options.

Options Hash (opts):

• :headers (Hash) — default: {} —

  Additional HTTP headers.

• :query (Hash) — default: {} —

  Additional URL query parameters.

• :timeout (Integer) — default: nil —

  The timeout for this request, in seconds. If no value is explicitly given then the timeout set globally for the connection will be used.

• :wait (Boolean) — default: true —

  If true wait for the response.

Returns:

• (DataCenter)

# File 'lib/ovirtsdk4/services.rb', line 6862

def add(data_center, opts = {})
  internal_add(data_center, DataCenter, ADD, opts)
end

#data_center_service(id) ⇒ DataCenterService

Reference to the service that manages a specific data center.

Parameters:

• id (String) —

  The identifier of the data_center.

Returns:

• (DataCenterService) —

  A reference to the data_center service.

# File 'lib/ovirtsdk4/services.rb', line 6972

def data_center_service(id)
  DataCenterService.new(self, id)
end

#list(opts = {}) ⇒ Array<DataCenter>

Lists the data centers.

The following request retrieves a representation of the data centers:

GET /ovirt-engine/api/datacenters HTTP/1.1

The above request performed with curl:

curl \
--request GET \
--cacert /etc/pki/ovirt-engine/ca.pem \
--header "Version: 4" \
--header "Accept: application/xml" \
--user "admin@internal:mypassword" \
https://myengine.example.com/ovirt-engine/api/datacenters

This is what an example response could look like:

<data_center href="/ovirt-engine/api/datacenters/123" id="123">
  <name>Default</name>
  <description>The default Data Center</description>
  <link href="/ovirt-engine/api/datacenters/123/networks" rel="networks"/>
  <link href="/ovirt-engine/api/datacenters/123/storagedomains" rel="storagedomains"/>
  <link href="/ovirt-engine/api/datacenters/123/permissions" rel="permissions"/>

  <link href="/ovirt-engine/api/datacenters/123/iscsibonds" rel="iscsibonds"/>
  <link href="/ovirt-engine/api/datacenters/123/quotas" rel="quotas"/>
  <local>false</local>
  <quota_mode>disabled</quota_mode>
  <status>up</status>
  <supported_versions>
    <version>
      <major>4</major>
      <minor>0</minor>
    </version>
  </supported_versions>
  <version>
    <major>4</major>
    <minor>0</minor>
  </version>
</data_center>

Note the id code of your Default data center. This code identifies this data center in relation to other resources of your virtual environment.

The data center also contains a link to the storage domains collection. The data center uses this collection to attach storage domains from the storage domains main collection.

The order of the returned list of data centers is guaranteed only if the sortby clause is included in the search parameter.

Parameters:

• opts (Hash) (defaults to: {}) —

  Additional options.

Options Hash (opts):

• :case_sensitive (Boolean) —

  Indicates if the search performed using the search parameter should be performed taking case into account. The default value is true, which means that case is taken into account. If you want to search ignoring case set it to false.

• :filter (Boolean) —

  Indicates if the results should be filtered according to the permissions of the user.

• :follow (String) —

  Indicates which inner links should be followed. The objects referenced by these links will be fetched as part of the current request. See here for details.

• :max (Integer) —

  Sets the maximum number of data centers to return. If not specified all the data centers are returned.

• :search (String) —

  A query string used to restrict the returned data centers.

• :headers (Hash) — default: {} —

  Additional HTTP headers.

• :query (Hash) — default: {} —

  Additional URL query parameters.

• :timeout (Integer) — default: nil —

  The timeout for this request, in seconds. If no value is explicitly given then the timeout set globally for the connection will be used.

• :wait (Boolean) — default: true —

  If true wait for the response.

Returns:

• (Array<DataCenter>)

  internal_get(LIST, opts)
end

#service(path) ⇒ Service

Locates the service corresponding to the given path.

Parameters:

• path (String) —

  The path of the service.

Returns:

• (Service) —

  A reference to the service.
