2017-10-20 Thread Chao Gao
pt_update_irq() is expected to return the vector number of periodic timer interrupt, which should be set in vIRR of vlapic or in PIR. Otherwise it would trigger the assertion in vmx_intr_assist(), please seeing https://lists.xenproject.org/archives/html/xen-devel/2017-10/msg00915.html. But it
