Hi, Éder
Thanks for your help. I finally boot my linux with setting
echo 1 > /proc/sys/vm/overcommit_memory
on the 16G RAM/16G Swap machine, which gem5 used 16G RAM and 4G swap.
I have no idea why gem5 eat up so much memory. I configure model is only 512MB
RAM and hda1 is 8G image installed ubuntu 16.04.4
Is it normal? How can I make gem5 use less memory?

Hello,
you could try this (superuser privileges are required):
grep -i 'killed process' /var/log/messages
Check if gem5 was killed by the OOM-killer.
As a quick workaround or just for testing and gathering more
information you could try this:
echo 1 > /proc/sys/vm/overcommit_memory
Documentation here:
https://www.kernel.org/doc/Documentation/sysctl/vm.txt
Best Regards,

Hello, Jason
It is not likely running out of menory, since I try my boot on
both 8G machine with 8G swap, and 16G machine with 2G swap. Both
failed. Anything else I can do to debug this issue?
Thanks.

Hello,
It looks like your host OS killed the gem5 process
"Program terminated with signal SIGKILL, Killed.
The program no longer exists."
Could you have run out of memory on the
host?
