Virtual CPU

Fields

id: u8

vCPU ID (0 = BSP, 1+ = APs)

state: VcpuState

Current execution state

registers: GuestRegisters

General-purpose registers

apic_id: u8

LAPIC ID for this vCPU

pending_ipis: Vec<IpiMessage>

Pending IPIs (queue)

is_bsp: bool

Whether this is the bootstrap processor

host_affinity: Option<u32>

Host thread affinity (which host CPU to schedule on)

sipi_vector: u8

SIPI vector (real-mode entry = vector * 0x1000)

vmcs_fields: BTreeMap<u32, u64>

VMCS field values for this vCPU
