KvmVcpu

Struct KvmVcpu 

Source
pub struct KvmVcpu { /* private fields */ }
Expand description

Virtual CPU implementation for Linux KVM.

Each vCPU represents a virtual processor that can execute guest code. vCPUs are created via the KVM VM file descriptor and run using the KVM_RUN ioctl.

Implementations§

Source§

impl KvmVcpu

Source

pub fn is_running(&self) -> bool

Returns whether the vCPU is currently running.

Source

pub fn running_flag(&self) -> Arc<AtomicBool>

Returns a clone of the running flag for external monitoring.

Source

pub fn signal_exit(&self)

Signals the vCPU to exit immediately.

This causes the next KVM_RUN to return immediately.

Source

pub fn setup_linux_boot( &self, entry_point: u64, boot_params_addr: u64, ) -> Result<(), HypervisorError>

Sets up initial register state for Linux boot (x86_64).

Source

pub fn set_io_in_data(&self, data: &[u8])

Provides data for an I/O IN instruction.

Source

pub fn set_mmio_read_data(&self, data: &[u8])

Provides data for an MMIO read.
