Crate hypervisor

A crate for abstracting the underlying kernel hypervisor used in crosvm.

Re-exports

• pub use crate::caps::*;
• pub use crate::x86_64::*;

Modules

• caps
• kvm
• x86_64

Structs

• ClockState
  The state of the paravirtual clock.
• Config
• IoParams
  Parameters describing an MMIO or PIO from the guest.
• IrqRoute
  A single route for an IRQ.
• MemRegion
  Range of GPA space. Starting from guest_address up to size.
• VcpuShutdownError
  A Vcpu shutdown may signify an error, such as a double or triple fault, or hypervisor specific reasons. This error covers all such cases.
• VcpuSignalHandle
  Handle to a virtual CPU that may be used to request a VM exit from within a signal handler.

Enums

• BalloonEvent
  This is intended for use with virtio-balloon, where a guest driver determines unused ranges and requests they be freed. Use without the guest’s knowledge is sure to break something.
• Datamatch
  Used in Vm::register_ioevent to indicate a size and optionally value to match.
• DeviceKind
  A device type to create with Vm.create_device.
• IoEventAddress
  An address either in programmable I/O space or in memory mapped I/O space.
• IoOperation
  Operation for Io and Mmio
• IrqSource
  A source of IRQs in an IrqRoute.
• IrqSourceChip
  The source chip of an IrqSource
• MPState
  The MPState represents the state of a processor.
• MemCacheType
  Signal to the hypervisor on kernels that support the KVM_CAP_USER_CONFIGURE_NONCOHERENT_DMA (or equivalent) that during user memory region (memslot) configuration, a guest page’s memtype should be considered in SLAT effective memtype determination rather than implicitly respecting only the host page’s memtype.
• ProtectionType
  Whether the VM should be run in protected mode or not.
• VcpuExit
  A reason why a VCPU exited. One of these returns every time Vcpu::run is called.
• VcpuShutdownErrorKind

Traits

• Hypervisor
  A trait for checking hypervisor capabilities.
• Vcpu
  A virtual CPU holding a virtualized hardware thread’s state, such as registers and interrupt state, which may be used to execute virtual machines.
• VcpuSignalHandleInner 🔒
  Signal-safe mechanism for requesting an immediate VCPU exit.
• Vm
  A wrapper for using a VM and getting/setting its state.

Type Aliases

• MemSlot
  An index in the list of guest-mapped memory regions.
