Hi, all:

I want to test some program, which requires a high precise time. (some
thing as rdtsc).

I tested rdtsc on different VMs, they are not consistant. (I am using
Xen 4.0, Fedora 13, 64 bit).

Is there a way to get consistant high precise time across different VMs?

Thanks very much!

Best!

Sam
