# This example shows how to set a custom serial number in a virtual
# machine:

# Create the connection to the server:
connection = OvirtSDK4::Connection.new(
  url:      'https://engine40.example.com/ovirt-engine/api',
  username: 'admin@internal',
  password: 'redhat123',
  ca_file:  'ca.pem',
  debug:    true,
  log:      Logger.new('example.log')
)

# Locate the virtual machines service and use it to find the virtual
# machine:
vms_service = connection.system_service.vms_service
vm = vms_service.list(search: 'name=myvm')[0]

# Locate the service that manages that specific virtual machine:
vm_service = vms_service.vm_service(vm.id)

# Use the "update" method to set a serial number policy and value:
vm_service.update(
  serial_number: {
    policy: OvirtSDK4::SerialNumberPolicy::CUSTOM,
    value:  'myserial'
  }
)

# Close the connection to the server:
connection.close
