Hello,

I joined the marss mailing list a few days ago. Currently, I have
prepared the simulation infrastructures with custom disk.
Since I have obtained the custom disk which was build by VirtualBox, I
just want to use it.
So, i changed the disk format from VDI to QCOW2. It works well with qemu.

However, when i run the start_sim
program(http://marss86.org/~marss86/index.php/Checkpoints_in_MARSS),
the marss exhibits errors like below.

ERROR: guest physical address 0xf023f432 is out of bounds

Also, the start_sim does not complete. So, I cannot measure any of
them. Below are log messages.

jeongseob@desktop:~/marss-0.4$ qemu/qemu-system-x86_64
~/marss/ubuntu_10.04.qcow2
Simulator is now waiting for a 'run' command.
PTLCALL type PTLCALL_ENQUEUE
MARSSx86::Command received : -run
  Completed       1582000 cycles,       1166439 commits:    106603 Hz,
   176123 insns/sec: rip 00007f33d01959c6


Of course, the image provided by officially marss, the start_sim works well.
However, i want to use my custom disk.

Does anyone who experience the issues ??
Please help me.

Thanks
- Ahn
