Expand description

Trait for VMM-specific contruction and runtime resources

Required Associated Types§

Source

type VmmConfig

VMM-specific configuration

Source

type VmRuntime: PetriVmRuntime

Runtime object

Required Methods§

Source

fn check_compat(firmware: &Firmware, arch: MachineArch) -> bool

Check whether the combination of firmware and architecture is supported on the VMM.

Source

fn quirks(firmware: &Firmware) -> (GuestQuirksInner, VmmQuirks)

Select backend specific quirks guest and vmm quirks.

Source

fn default_servicing_flags() -> OpenHclServicingFlags

Get the default servicing flags (based on what this backend supports)

Source

fn create_guest_dump_disk() -> Result<Option<(Arc<TempPath>, Box<dyn FnOnce() -> Result<Box<dyn ReadWriteSeek>>>)>>

Create a disk for guest crash dumps, and a post-test hook to open the disk to allow for reading the dumps.

Source

fn new(resolver: &ArtifactResolver<'_>) -> Self

Resolve any artifacts needed to use this backend

Source

fn run<'life0, 'async_trait>( self, config: PetriVmConfig, modify_vmm_config: Option<impl 'async_trait + FnOnce(Self::VmmConfig) -> Self::VmmConfig + Send>, resources: &'life0 PetriVmResources, ) -> Pin<Box<dyn Future<Output = Result<Self::VmRuntime>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Create and start VM from the generic config using the VMM backend

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
