There is a window where we may miss the current request in the
notification period when the work flow is as the following:
CPUx + + CPUr
| |
| +--+
| | | Handle pending req
| <--+
+--+ |
| | Set req flag |
<--+ |
+------------------>---+
| Send NMI | | Handle NMI
| <--+
| |
| |
| +--> vCPU enter
| |
+ +
So, this patch enables the NMI-window exiting to trigger the next vmexit
once there is no "virtual-NMI blocking" after vCPU enter into VMX non-root
mode. Then we can process the pending request on time.
