Hi, all:

          This is my first time to use Marss simulator. But I cannot run the 
parsecROI benchmarks.

          I download the parsecROI benchmarks and convert it to qcow2 type as 
instructions on website.
          Then I create the checkpoints using qemu-img command and results show 
that checkpoints have been created successfully.

qemu/qemu-img info parsecROI.qcow2
image: parsecROI.qcow2
file format: qcow2
virtual size: 4.7G (5000000000 bytes)
disk size: 5.9G
cluster_size: 65536

11        streamcluster          123M 2012-09-03 14:45:39   00:00:25.826

           When I start the simulator: qemu/qemu-system-x86-64 parsecROI.qcow2 
and switch to monitor screen (ALT+CTL+2)
           (Qemu) loadvm blackscholes
           After I input the command above, the qemu program stalls and window 
freezes.
           The simulator seems not to load the checkpoint correctly.

          I also run the simulator using configuration file just as 
ISCA2012-tutorial says: qemu/qemu-systme-x86-64 -c uti.cfg parsecROI
          I can find the log files, but the results shows that the benchmarks 
do not run at all.

          I have struggled for the problems for long time, but  could not 
figure out what's wrong with my operations?
          Thanks for any suggestions.

       Shuai
