Creates a new implementation of the service.
@param connection [Connection] The connection to be used by this service.
@param path [String] The relative path of this service, for example `vms/123/disks`.
@api private

Creates a virtual machine snapshot.
For example, to create a new snapshot for virtual machine `123` send a request like this:
POST /ovirt-engine/api/vms/123/snapshots
With a request body like this:
<snapshot>
<description>My snapshot</description>
</snapshot>
@param snapshot [Snapshot] The `snapshot` to add.
@param opts [Hash] Additional options.
@return [Snapshot]
# File lib/ovirtsdk4/services.rb, line 21205 def add(snapshot, opts = {}) if snapshot.is_a?(Hash) snapshot = OvirtSDK4::Snapshot.new(snapshot) end query = {} request = HttpRequest.new(method: :POST, url: @path, query: query) begin writer = XmlWriter.new(nil, true) SnapshotWriter.write_one(snapshot, writer) request.body = writer.string ensure writer.close end response = @connection.send(request) case response.code when 200, 201, 202 begin reader = XmlReader.new(response.body) return SnapshotReader.read_one(reader) ensure reader.close end else check_fault(response) end end
Returns the representation of the object managed by this service.
@param opts [Hash] Additional options.
@option opts [Integer] :max Sets the maximum number of snapshots to return. If not specified all the snapshots are returned.
@return [Array<Snapshot>]
# File lib/ovirtsdk4/services.rb, line 21241 def list(opts = {}) query = {} value = opts[:max] unless value.nil? value = Writer.render_integer(value) query['max'] = value end request = HttpRequest.new(method: :GET, url: @path, query: query) response = @connection.send(request) case response.code when 200 begin reader = XmlReader.new(response.body) return SnapshotReader.read_many(reader) ensure reader.close end else check_fault(response) end end
Locates the service corresponding to the given path.
@param path [String] The path of the service.
@return [Service] A reference to the service.
# File lib/ovirtsdk4/services.rb, line 21281 def service(path) if path.nil? || path == '' return self end index = path.index('/') if index.nil? return snapshot_service(path) end return snapshot_service(path[0..(index - 1)]).service(path[(index +1)..-1]) end
Locates the `snapshot` service.
@param id [String] The identifier of the `snapshot`.
@return [SnapshotService] A reference to the `snapshot` service.
# File lib/ovirtsdk4/services.rb, line 21270 def snapshot_service(id) SnapshotService.new(@connection, "#{@path}/#{id}") end
Returns an string representation of this service.
@return [String]
