Question about time measure in Guest Windows
Hi:
I intend to use RDTSC to make some time tests in Xen guest WinXP. However, from Intel Developer''s Manual I noticed that RDTSC will cause VMExit if "RETSC exiting" VM-Execution control field is 1. So I wonder: How to query VM-Execution control field in a programmable way?
BTW: On Intel Developer''s Manual, it mentioned a method using IA32_VMX_PROCBASED_CTLS MSR,
