I don't think there is any TSC emulation (or more properly "rdtsc emulation") in 3.4.x, certainly not without a special Xen boot option. The TSC delta is troubling... if you hadn't said you had turned off all power management, I would have guessed a problem with C-state management. Maybe Xen is discovering some power management capability not visible in BIOS settings? _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
