Struct vm_control::VcpuSuspendGuard

pub struct VcpuSuspendGuard<'a> {
    pub(crate) saved_run_mode: VmRunMode,
    pub(crate) kick_vcpus: &'a dyn Fn(VcpuControl),
}

A guard to guarantee that all the vCPUs are suspended during the scope.

When this guard is dropped, it rolls back the state of CPUs.

Fields

saved_run_mode: VmRunMode

kick_vcpus: &'a dyn Fn(VcpuControl)

Implementations

impl<'a> VcpuSuspendGuard<'a>

pub fn new( kick_vcpus: &'a impl Fn(VcpuControl), vcpu_num: usize ) -> Result<Self>

Check the all vCPU state and suspend the vCPUs if they are running.

This returns VcpuSuspendGuard to rollback the vcpu state.

Arguments

• kick_vcpus - A funtion to send VcpuControl message to all the vCPUs and interrupt them.
• vcpu_num - The number of vCPUs.
