Enum VmAction 

pub enum VmAction {
    PvTimerConfig = 107,
    Halt = 108,
}

IO-port actions intercepted at the hypervisor level (in run_vcpu) before they ever reach the sandbox outb handler. These are split from OutBAction so the outb handler does not need unreachable match arms for ports it can never see.

Variants

PvTimerConfig = 107

IO port for PV timer configuration. The guest writes a 32-bit LE value representing the desired timer period in microseconds. A value of 0 disables the timer.

Halt = 108

IO port the guest writes to signal “I’m done” to the host. This replaces the hlt instruction for halt signaling so that KVM’s in-kernel LAPIC (which absorbs HLT exits) does not interfere with hyperlight’s halt-based guest-host protocol.

Trait Implementations

impl TryFrom<u16> for VmAction

type Error = Error

The type returned in the event of a conversion error.

fn try_from(val: u16) -> Result<Self>

Performs the conversion.
