 - bonnie++-1.03
 - ltp-full-20060306
 - iozone3_191
 - lmbench-3.0-a5

TEST ENVIRONMENT
    Machine          : Tiger4
    KERN             : 2.6.16.13-xen
    changeset        : 10443
    Dom0 OS          : RHEL4 U2 (no SMP)
    DomU OS          : RHEL4 U2 (2P)
    No. of DomU's    : 1

SUMMARY:
     - We used 2cpus on the domU testing.
     - We used sched="credit".
     - We applied the following patch, which have been already
