Required Methods

fn caps(&self) -> &X86PartitionCapabilities

Gets the partition’s capabilities.

fn commit(&mut self) -> Result<(), Self::Error>

Commits any state changes made with the set_* methods.

fn hypercall(&mut self) -> Result<HypercallMsrs, Self::Error>

Gets the specified state.

fn set_hypercall(&mut self, value: &HypercallMsrs) -> Result<(), Self::Error>

Sets the specified state.

fn reftime(&mut self) -> Result<ReferenceTime, Self::Error>

Gets the specified state.

fn set_reftime(&mut self, value: &ReferenceTime) -> Result<(), Self::Error>

Sets the specified state.

fn reference_tsc_page(&mut self) -> Result<ReferenceTscPage, Self::Error>

Gets the specified state.

fn set_reference_tsc_page( &mut self, value: &ReferenceTscPage, ) -> Result<(), Self::Error>

Sets the specified state.

Provided Methods

fn save_all(&mut self) -> Result<VmSavedState, StateError<Self::Error>>

Save all state that can be restored by a call to restore.

fn restore_all( &mut self, state: &VmSavedState, ) -> Result<(), StateError<Self::Error>>

Restore state elements saved in save state.

fn reset_all( &mut self, vp_info: &X86VpInfo, ) -> Result<(), StateError<Self::Error>>

Resets all the state elements to their initial state (after machine reset).

fn check_reset_all(&mut self, vp_info: &X86VpInfo)

Validates that all state elements are in their initial state (after machine reset).

fn inspect_all(&mut self, req: Request<'_>)
