Struct VpRunner 

pub struct VpRunner<'a> { /* private fields */ }

Implementations

impl<'a> VpRunner<'a>

pub fn complete_exit(&mut self) -> Result<Exit<'_>, Error>

Completes the current exit without running the VP further.

This may generate more exits.

pub fn run(&mut self) -> Result<Exit<'_>, Error>

Continues running the VP.

Runs until an exit occurs or interrupted by a signal or a call to Processor::force_exit.

pub fn check_or_request_interrupt_window(&mut self) -> bool

Request an exit when the interrupt window opens.

Returns true if the window is already open, in which case no request is registered, and any earlier request is withdrawn.

pub fn interrupt_window_requested(&mut self) -> bool

Returns whether an exit is requested for when the interrupt window opens (see Self::check_or_request_interrupt_window).

The request stays registered until Self::run returns Exit::InterruptWindow, or until Self::check_or_request_interrupt_window finds the window open.

pub fn queue_extint_interrupt(&mut self, vector: u8) -> Result<(), Error>

Queues an extint interrupt with KVM_INTERRUPT.

KVM delivers the interrupt once the guest can take it, exiting from a nested guest first if needed. But KVM has no way to report or withdraw a queued extint; KVM_GET_VCPU_EVENTS never exposes the queued vector.

Caller must ensure that either it has received a Exit::InterruptWindow exit, or that Self::check_or_request_interrupt_window has returned true.
