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
# File lib/ovirtsdk4/services.rb, line 31324 def initialize(connection, path) @connection = connection @path = path end
Attach target device to given virtual machine.
Example:
POST /ovirt-engine/api/vms/123/hostdevices
With request body of type <<types/host_device,HostDevice>>, for example
<host_device id=“123” />
NOTE: A necessary precondition for a successful host device attachment is that the virtual machine must be pinned to exactly one host. The device ID is then taken relative to this host.
NOTE: Attachment of a PCI device that is part of a bigger IOMMU group will result in attachment of the remaining devices from that IOMMU group as “placeholders”. These devices are then identified using the `placeholder` attribute of the <<types/host_device,HostDevice>> type set to `true`.
In case you want attach a device that already serves as an IOMMU placeholder, simply issue an explicit Add operation for it, and its `placeholder` flag will be cleared, and the device will be accessible to the virtual machine.
@param device [HostDevice] The host device to be attached to given virtual machine.
@param opts [Hash] Additional options.
@return [HostDevice]
# File lib/ovirtsdk4/services.rb, line 31362 def add(device, opts = {}) if device.is_a?(Hash) device = OvirtSDK4::HostDevice.new(device) end query = {} request = HttpRequest.new(method: :POST, url: @path, query: query) begin writer = XmlWriter.new(nil, true) HostDeviceWriter.write_one(device, 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 HostDeviceReader.read_one(reader) ensure reader.close end else check_fault(response) end end
Returns a reference to the service that manages a specific host device attached to given virtual machine.
@param id [String] The identifier of the `device`.
@return [VmHostDeviceService] A reference to the `device` service.
# File lib/ovirtsdk4/services.rb, line 31427 def device_service(id) VmHostDeviceService.new(@connection, "#{@path}/#{id}") end
List the host devices assigned to given virtual machine.
@param opts [Hash] Additional options.
@option opts [Integer] :max Sets the maximum number of devices to return. If not specified all the devices are returned.
@return [Array<HostDevice>]
# File lib/ovirtsdk4/services.rb, line 31398 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 HostDeviceReader.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.

Returns an string representation of this service.
@return [String]
