    KVM: Route irq 0 to vcpu 0 exclusively · 8c35f237
    Avi Kivity authored
    Some Linux versions allow the timer interrupt to be processed by more than
    one cpu, leading to hangs due to tsc instability.  Work around the issue
    by only disaptching the interrupt to vcpu 0.
    
    Problem analyzed (and patch tested) by Sheng Yang.
