FS on Ubuntu 16.04 - MortezaRamezani/gem5 GitHub Wiki
since sfdisk has changed, the default gem5img is not working properly. in the meantime we can do this, after creating the image (either with gem5img or dd):
dd if=/dev/zero of=ubuntu-14.04.img bs=1 count=0 seek=8G
and set up loop device:
sudo losetup /dev/loop0 ubuntu-14.04.img
install gparted, then:
sudo gparted /dev/loop0
then create partition table with msdos and create a new partition with ext2.
confirm with parted using following link:

then detach the loop device:
sudo losetup -d /dev/loop0
follow the rest from Mario and Jason websites.
