Problem correlating TSC read from domU with Xentrace's TSC
...rt both trace is
completely disjointed. TSC values from Xentrace is always greater than
what guest VM see, even if I start capturing Xen''s trace 30s before
capturing trace in guest VM.
I understand that Xen don''t emulate rdtsc() for PV guest and Xentrace
also read rdtsc() during __insert_record(). However, I don''t
understand what cause my issue. Any suggestion? I am using Xen
4.1.1 on Fedora 15
