Enum VmAction

Source

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

Expand description

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.
