Quick Start
Download vmlinuz, initrd and qcow2 image from the release page, and start your virtual machine with QEMU.
In most cases, you want to access the virtual machine via SSH, so don’t forget to add a port forwarding or bridge your network interfaces.
Below are a few quick start command lines. Note the file names should be replaced by the ones you download.

Loongarch64
So far, Loongarch64 Debian ports are not complete but we can boot Loong Archlinux and run debian userland inside.
docker run -p 5555:5555 -v `pwd`:/work --rm -it lazymio/qemu-full:v8.2.0 \
qemu-system-loongarch64 -m 1024m -cpu la464-loongarch-cpu \

-hda ./debian-bullseye-loong64.qcow2 --nographic \
-nic user,model=virtio-net-pci,hostfwd=tcp::5555-:22
After the system is up, SSH into it and use:
[root@debian-bullseye-loong64 ~]# cd /debian/
[root@debian-bullseye-loong64 debian]# chroot .
root@debian-bullseye-loong64:/# cat /etc/issue
Debian GNU/Linux trixie/sid \n \l
root@debian-bullseye-loong64:/# uname -a
Linux debian-bullseye-loong64 6.7.0-rc2-2 #1 SMP PREEMPT Mon, 27 Nov 2023 08:42:49 +0000 loongarch64 GNU/Linux
root@debian-bullseye-loong64:/# apt
apt 2.7.7 (loong64)
Usage: apt [options] command
apt is a commandline package manager and provides commands for
searching and managing as well as querying information about packages.
It provides the same functionality as the specialized APT tools,
like apt-get and apt-cache, but enables options more suitable for
interactive use by default.
Most used commands:
list - list packages based on package names
search - search in package descriptions
show - show package details
install - install packages
reinstall - reinstall packages
remove - remove packages
autoremove - automatically remove all unused packages
update - update list of available packages
upgrade - upgrade the system by installing/upgrading packages
full-upgrade - upgrade the system by removing/installing/upgrading packages
edit-sources - edit the source information file
satisfy - satisfy dependency strings
See apt(8) for more information about the available commands.
Configuration options and syntax is detailed in apt.conf(5).
Information about how to configure sources can be found in sources.list(5).
Package and version choices can be expressed via apt_preferences(5).
Security details are available in apt-secure(8).
This APT has Super Cow Powers.
root@debian-bullseye-loong64:/#
Or using a docker approach:
pacmam -Syu docker
mkdir -p /etc/docker
# This is important to avoid ip addresses conflicting with host's docker!
echo > /etc/docker/daemon.json <<EOF
{
"default-address-pools": [
{"base": "10.99.0.0/16", "size":24}
]
}
EOF
systemctl start docker && systemctl enable docker
echo "FROM scratch" > /debian/Dockerfile
echo "ADD . /" >> /debian/Dockerfile
cd /debian && docker build -t debian_rootfs .
docker run -it --rm debian_rootfs bash
Once Debian ports is available we can jump over ArchLinux and boot Debian directly.
Usage
SSH
Two users created: root:root and debian:debian and ssh server is up by default.
Resize disk
On host:
qemu-img resize ./debian-bullseye-loong64.qcow2 16G
On emulated targets:
parted /dev/vda resizepart 1 100%
resize2fs /dev/vda
reboot
