Available on crate features vmm-core and vmm-process only.

Error caused during a VmmProcess operation.

Variants

IncorrectState(VmmProcessState)

The VmmProcess was in an incorrect VmmProcessState, which is not allowed for the requested operation.

ApiSocketDisabled

Attempted to send an API request or send Ctrl+Alt+Del (which is done via an API request) with the API socket being disabled.

ChangeOwnerError(ChangeOwnerError)

A ChangeOwnerError occurred while changing the ownership of the VMM’s API socket file.

RequestError(Box<dyn Error + Send + Sync>)

Completing an API request failed due to an HTTP error. The actual error is boxed and opaque in order not to expose the underlying HTTP connection pool’s implementation, which is currently that of hyper_util.

InvalidUri

A given URI for an API request was incorrect.

Fields

uri: String

The invalid URI of the API request.

error: InvalidUri

The http::uri::InvalidUri error with the reason for the URI being invalid.

SigkillError(Error)

An I/O error occurred while attempting to send a SIGKILL signal via the ProcessHandle.

CtrlAltDelRequestInvalid(Error)

The Ctrl+Alt+Del HTTP request was invalid due to an http::Error. This is usually caused by an internal bug in the library.

CtrlAltDelRequestDenied(StatusCode)

The Ctrl+Alt+Del HTTP request was denied by the API with the given unsuccessful StatusCode.

ProcessWaitFailed(Error)

An I/O error occurred while waiting for the process to exit via the ProcessHandle.

ExecutorError(VmmExecutorError)

A VmmExecutorError occurred while performing a prepare/invoke/cleanup invocation via the VmmExecutor of the VmmProcess.

ProcessHandlePipesError(ProcessHandlePipesError)

A ProcessHandlePipesError occurred while attempting to take out pipes via the ProcessHandle.

ResourceSystemError(ResourceSystemError)

A ResourceSystemError occurred while performing manual synchronization with the ResourceSystem after a VmmExecutor prepare/invoke/cleanup invocation.

Trait Implementations

impl Debug for VmmProcessError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for VmmProcessError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for VmmProcessError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
