This patch checkes the IDT_VECTORING_INFO_FIELD on vmx_intr_assist, and if it is set, then copy it to VM_ENTRY_INTR_INFO_FIELD and return. Though this method, we can avoid interrupt lost.

More information for IDT_VECTORING_INFO_FIELD can be seen on "Information for VM Exits That Occur During Event Delivery" section on vmx specification.

Hope I explained the issue clearly.

Thanks, it's certainly more helpful than your reference manual. :-)
