Dear Waliullah,
I think that the image has a gem5_init script that executes the m5
exit command. You can use the image from gem5 resources
(http://dist.gem5.org/dist/v21-2/images/x86/ubuntu-18-04/x86-ubuntu.img.gz)
with vmlinux-5.4.49 kernel
(http://dist.gem5.org/dist/v21-2/kernels/x86/static/vmlinux-5.4.49).
Then you need to emulate the image and change the gem5_init.sh in
order to get the terminal:
sudo apt-get install qemu qemu-user-static qemu-user
sudo mount -o loop,offset=1048576
$HOME/COSSIM/kernels/disks/x86-ubuntu.img /mnt
cd /mnt
sudo mount --bind /proc /mnt/proc
sudo mount --bind /dev /mnt/dev
sudo chroot .
nano root/gem5_init.sh #Change the line 21 from m5 exit to /bin/sh
exit
# now we are back to the host system
cd
sudo umount /mnt/proc
sudo umount /mnt/dev
sudo umount /mnt
Now you can simulate using the gem5.
Best regards,
Nikos

Hi,
I am a new user trying to run Gem5 in FS mode. My command line is
given bellow. I also attached a terminal to see the output.
Everything looks good except Gem5 exit after the boot process
finishes. On Gem5 run terminal I got the message
"[cid:image004.png@01D8394B.885BD600]".
Shouldn't I see a linux command prompt in the attached terminal
instead of exiting after boot complete.
Just wondering if the disk image I am using (downloaded from
gs://dist/gem5.org/dist/current/images/x86) has any init script that
causes this exit?
Appreciate your help.
Thanks
Here is my command line.

Here is the output from gem5:
