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. :-) -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
