Struct GuestMemoryManager 

pub struct GuestMemoryManager { /* private fields */ }

The OpenVMM memory manager.

Implementations

impl GuestMemoryManager

pub fn client(&self) -> GuestMemoryClient

Returns an object to access guest memory.

pub fn device_memory_mapper(&self) -> DeviceMemoryMapper

Returns an object to map device memory into the VM.

pub fn dma_mapper_client(&self) -> DmaMapperClient

Returns a client for registering DMA mappers (VFIO, iommufd).

pub fn ram_visibility_control(&self) -> RamVisibilityControl

Returns an object for manipulating the visibility state of different RAM regions.

pub fn shared_memory_backing(&self) -> Option<SharedMemoryBacking>

Returns the shared memory resources that can be used to reconstruct the memory backing.

The returned mappable can be passed back via RamBackingRequest::existing_mappable to create a new memory manager with the same memory state. Only one instance of this type should be managing a given memory backing at a time, though, or the guest may see unpredictable results.

Returns None unless there is exactly one backing and it is file-backed. This currently means multi-backing and private-memory configurations cannot be restarted.

pub async fn attach_partition( &mut self, vtl: Vtl, partition: &Arc<dyn PartitionMemoryMap>, process: Option<RemoteProcess>, ) -> Result<(), PartitionAttachError>

Attaches the guest memory to a partition, mapping it to the guest physical address space.

If process is provided, then allocate a VA range in that process for the guest memory, and map the memory into the partition from that process. This is necessary to work around WHP’s lack of support for mapping multiple partitions from a single process.

TODO: currently, all VTLs will get the same mappings–no support for per-VTL memory protections is supported.

Trait Implementations

impl Debug for GuestMemoryManager

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

Formats the value using the given formatter.

impl Inspect for GuestMemoryManager

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

Inspects the object.
