Comment 6 Qin Guan 2012-02-20 09:59:50 UTC 
Verify this problem with build version:
2.6.18-238.34.1.el5xen
xen-3.0.3-120.el5_6.5

Steps:
1. Specify "hpet=0" in guest conf, and then check the guest dmesg:
# dmesg | grep time.c
time.c: Using 3.579545 MHz WALL PM GTOD PM timer.
time.c: Detected 2705.703 MHz processor.

2. Do not specify the option "hpet" or specify "hpet=1" in guest conf, and then check the guest dmesg:
# dmesg | grep time.c
time.c: Using 84.553375 MHz WALL HPET GTOD HPET timer.
time.c: Detected 2705.701 MHz processor.

Change status to VERIFIED.
