Hello, As for I am not familiar with the gem5. I would like to custom disk images following the gem5.googlesource.com  gem5-resources to make a PARSEC disk image. I followed the instructions as the README.me, but I encounter some errors. The error information is shown as follow: qemu: output will be in this color. ==> qemu: Retrieving ISO ==> qemu: Trying http://old-releases.ubuntu.com/releases/18.04.2/ubuntu-18.04.2-server-amd64.iso ==> qemu: Trying http://old-releases.ubuntu.com/releases/18.04.2/ubuntu-18.04.2-server-amd64.iso?checksum=md5%3A34416ff83179728d54583bf3f18d42d2 ==> qemu: http://old-releases.ubuntu.com/releases/18.04.2/ubuntu-18.04.2-server-amd64.iso?checksum=md5%3A34416ff83179728d54583bf3f18d42d2 => /home/gem5/parsec/disk-image/packer_cache/e94c06241a5e6ba0c4b9618ddcda39ba2ee27e9a.iso ==> qemu: Creating floppy disk...     qemu: Copying files flatly from floppy_files     qemu: Copying file: shared/preseed.cfg     qemu: Done copying files from floppy_files     qemu: Collecting paths from floppy_dirs     qemu: Resulting paths from floppy_dirs : []     qemu: Done copying paths from floppy_dirs ==> qemu: Creating required virtual machine disks ==> qemu: Starting HTTP server on port 8413 ==> qemu: Found port for communicator (SSH, WinRM, etc): 2359. ==> qemu: Looking for available port between 5900 and 6000 on 127.0.0.1 ==> qemu: Starting VM, booting from CD-ROM     qemu: The VM will be run headless, without a GUI.

And another question is that how can I run MPI  in the FS mode? Thanks in advance. Zhang Meng

Hi, It's not clear from the error log where the problem is, but it does indicate that qemu failed to start. My suggestion is to check the path of the qemu binary (i.e. this line https://gem5.googlesource.com/public/gem5-resources/+/refs/heads/develop/src/parsec/disk-image/parsec/parsec.json#44). If the host does not support KVM, you'll need to remove this line ( https://gem5.googlesource.com/public/gem5-resources/+/refs/heads/develop/src/parsec/disk-image/parsec/parsec.json#9). If the problem persists, please run packer with the environment variable PACKER_LOG=1. To install MPI, you can add the shell commands to install MPI to the file disk-image / parsec / parsec-install.sh Regards, Hoa Nguyen On Tue, Oct 19, 2021, 7:50 PM 等价无穷小 via gem5-users <gem5-users(a)gem5.org> wrote: > Hello, > > As for I am not familiar with the gem5.
