Package vim25 provides a minimal client implementation to use with other packages in the vim25 tree. The code in this package intentionally does not take any dependendies outside the vim25 tree.

The client implementation in this package embeds the soap.Client structure. Additionally, it stores the value of the session's ServiceContent object. This object stores references to a variety of subsystems, such as the root property collector, the session manager, and the search index. The client is fully functional after serialization and deserialization, without the need for additional requests for initialization.

func IsTemporaryNetworkError added in v0.24.1

func IsTemporaryNetworkError(err error) bool

IsTemporaryNetworkError returns false unless the error implements a Temporary() bool method such as url.Error and net.Error. Otherwise, returns the value of the Temporary() method.

func Retry

func Retry(roundTripper soap.RoundTripper, fn RetryFunc, retryAttempts soap.RoundTripper

Retry wraps the specified soap.RoundTripper and invokes the specified RetryFunc. The RetryFunc returns whether or not to retry the call, and if so, how long to wait before retrying. If the result of this function is to not retry, the original error is returned from the RoundTrip function. The soap.RoundTripper will return the original error if retryAttempts is specified and reached.

func RetryTemporaryNetworkError added in v0.24.1

func RetryTemporaryNetworkError(err error) (bool, time.Duration)

RetryTemporaryNetworkError returns a RetryFunc that returns IsTemporaryNetworkError(err)


type Client

type Client struct {

	ServiceContent types.ServiceContent

	// RoundTripper is a separate field such that the client's implementation of
	// the RoundTripper interface can be wrapped by separate implementations for
	// extra functionality (for example, reauthentication on session timeout).
	RoundTripper soap.RoundTripper

Client is a tiny wrapper around the vim25/soap Client that stores session specific state (i.e. state that only needs to be retrieved once after the client has been created). This means the client can be reused after serialization without performing additional requests for initialization.

func NewClient

func NewClient(ctx context.Context, rt soap.RoundTripper) (*Client, error)

NewClient creates and returns a new client with the ServiceContent field filled in.

func (*Client) IsVC added in v0.4.0

func (c *Client) IsVC() bool

IsVC returns true if we are connected to a vCenter

func (*Client) MarshalJSON

func (c *Client) MarshalJSON() ([]byte, error)

func (*Client) Path added in v0.23.0

func (c *Client) Path() string

Path returns vim25.Path (see cache.Client)

func (*Client) RoundTrip

func (c *Client) RoundTrip(ctx context.Context, req, res soap.HasFault) error

RoundTrip dispatches to the RoundTripper field.

func (*Client) UnmarshalJSON

func (c *Client) UnmarshalJSON(b []byte) error

func (*Client) UseServiceVersion added in v0.21.0

func (c *Client) UseServiceVersion(kind ...string) error

UseServiceVersion sets soap.Client.Version to the current version of the service endpoint via /sdk/vimServiceVersions.xml

func (*Client) Valid

func (c *Client) Valid() bool

Valid returns whether or not the client is valid and ready for use. This should be called after unmarshalling the client.

type RetryFunc

type RetryFunc func(err error) (retry bool, delay time.Duration)

func TemporaryNetworkError

func TemporaryNetworkError(n int) RetryFunc

TemporaryNetworkError is deprecated. Use Retry() with RetryTemporaryNetworkError and retryAttempts instead.

package main

import (


func main() {
	simulator.Run(func(ctx context.Context, c *vim25.Client) error {
		// Configure retry handler
		delay := time.Millisecond * 100
		retry := func(err error) (bool, time.Duration) {
			return vim25.IsTemporaryNetworkError(err), delay
		c.RoundTripper = vim25.Retry(c.Client, retry, 3)

		vm, err := find.NewFinder(c).VirtualMachine(ctx, "DC0_H0_VM0")
		if err != nil {
			return err

		// Tell vcsim to respond with 502 on the 1st request
		simulator.StatusSDK = http.StatusBadGateway

		state, err := vm.PowerState(ctx)
		if err != nil {
			return err


		return nil
