Trait with the minimal methods needed to run the partition.

Required Methods

fn initial_vp_state_source(&self) -> InitialVpStateSource

Returns the source of the initial virtual processor state.

fn reset(&mut self) -> Result<()>

Resets the partition.

fn scrub_vtl(&mut self, vtl: Vtl) -> Result<()>

Scrubs the VTL state for a partition.

fn accept_initial_pages(&mut self, pages: Vec<InitialPageImport>) -> Result<()>

Finalizes initial page imports on behalf of the loader.

Provided Methods

fn freeze_time(&mut self)

Freezes backend partition time, if owned and supported by this backend. All VPs have stopped before this is called.

fn thaw_time(&mut self)

Thaws backend partition time before VP execution can start. This must be a no-op for time that is already running.

fn guest_os_id(&self) -> u64

Returns the guest OS ID (from HV_X64_MSR_GUEST_OS_ID).

Returns 0 if the guest hasn’t written the MSR (unenlightened guest) or if the backend doesn’t support reading it.
