Request Body Parameters:

Name Type Description
bold = required
spec update_spec Specification for updating the virtual serial port.
spec.yield_on_poll boolean CPU yield behavior. If set to true, the virtual machine will periodically relinquish the processor if its sole task is polling the virtual serial port. The amount of time it takes to regain the processor will depend on the degree of other virtual machine activity on the host.

This field may be modified at any time, and changes applied to a connected virtual serial port take effect immediately.

Optional. If unset, the value is unchanged.

spec.backing backing_spec Physical resource backing for the virtual serial port.

This field may only be modified if the virtual machine is not powered on or the virtual serial port is not connected.

Optional. If unset, the value is unchanged.

spec.backing.type string Backing type for the virtual serial port.

Defines the valid backing types for a virtual serial port. Value is one of:
FILE: Virtual serial port is backed by a file.
HOST_DEVICE: Virtual serial port is backed by a device on the host where the virtual machine is running.
PIPE_SERVER: Virtual serial port is backed by a named pipe server. The virtual machine will accept a connection from a host application or another virtual machine on the same host. This is useful for capturing debugging information sent through the virtual serial port.
PIPE_CLIENT: Virtual serial port is backed by a named pipe client. The virtual machine will connect to the named pipe provided by a host application or another virtual machine on the same host. This is useful for capturing debugging information sent through the virtual serial port.
NETWORK_SERVER: Virtual serial port is backed by a network server. This backing may be used to create a network-accessible serial port on the virtual machine, accepting a connection from a remote system.
NETWORK_CLIENT: Virtual serial port is backed by a network client. This backing may be used to create a network-accessible serial port on the virtual machine, initiating a connection to a remote system.

spec.backing.file string Path of the file backing the virtual serial port.

Optional. It is only relevant when type has value FILE. This field is optional and it is only relevant when the value of type is FILE.

spec.backing.host_device string Name of the device backing the virtual serial port.

Optional. It is only relevant when type has value HOST_DEVICE. If unset, the virtual serial port will be configured to automatically detect a suitable host device.

spec.backing.pipe string Name of the pipe backing the virtual serial port.

Optional. It is only relevant when type has value [PIPE_SERVER, PIPE_CLIENT]. This field is optional and it is only relevant when the value of type is one of PIPE_SERVER or PIPE_CLIENT.

spec.backing.no_rx_loss boolean Flag that enables optimized data transfer over the pipe. When the value is true, the host buffers data to prevent data overrun. This allows the virtual machine to read all of the data transferred over the pipe with no data loss.

Optional. It is only relevant when type has value [PIPE_SERVER, PIPE_CLIENT]. If unset, defaults to false.

spec.backing.network_location URI URI specifying the location of the network service backing the virtual serial port.

Optional. It is only relevant when type has value [NETWORK_SERVER, NETWORK_CLIENT]. This field is optional and it is only relevant when the value of type is one of NETWORK_SERVER or NETWORK_CLIENT.

spec.backing.proxy URI Proxy service that provides network access to the network backing. If set, the virtual machine initiates a connection with the proxy service and forwards the traffic to the proxy.

Optional. It is only relevant when type has value [NETWORK_SERVER, NETWORK_CLIENT]. If unset, no proxy service should be used.

spec.start_connected boolean Flag indicating whether the virtual device should be connected whenever the virtual machine is powered on.

Optional. If unset, the value is unchanged.

spec.allow_guest_control boolean Flag indicating whether the guest can connect and disconnect the device.

Optional. If unset, the value is unchanged.

Errors:

HTTP Status Code Type Description
500 error if the system reports an error while responding to the request.
404 not_found if the virtual machine or virtual serial port is not found.
400 not_allowed_in_current_state if one or more of the fields specified in the spec parameter cannot be modified due to the current power state of the virtual machine or the connection state of the virtual serial port.
400 resource_busy if the virtual machine is busy performing another operation.
400 resource_inaccessible if the virtual machine's configuration state cannot be accessed.
503 service_unavailable if the system is unable to communicate with a service to complete the request.
401 unauthenticated if the user can not be authenticated.
