This QEMU has support for I2C needed belowbuild of QEMU is necessary to use the I2C device with the argument -device ds1338,address=0x20 as described later in the document.

Build as:

Code Block
git clone https://github.com/vireshk/qemu
mkdir -p build/qemu
mkdir -p build/qemu-install
cd build/qemu
../../qemu/configure \
    --target-list="aarch64-softmmu" \
    --prefix="$(cd ../qemu-install; pwd)" \
    --enable-fdt --enable-slirp --enable-strip \
    --disable-docs \
    --disable-gtk --disable-opengl --disable-sdl \
    --disable-dbus-display --disable-virglrenderer \
    --disable-vte --disable-brlapi \
    --disable-alsa --disable-jack --disable-oss --disable-pa
  make -j10
  make install

...

If guestfish is not available, as a last resort you can scp the files while QEMU is running with scp -p P 8022 file root@localhost:/root/. To get an ssh login use ssh -p root@loclahost (Capitol P for scp and lowercase p for ssh.). The Debian nocloud image recommended at the next step has the default credentials root and no password. You will need to install an OpenSSH server apt update && apt install -y openssh-server then enable it by:

  • edit /etc/ssh/sshd_config and un-comment the lines:

  • Code Block
    Port 22
AddressFamily any
ListenAddress 0.0.0.0
ListenAddress ::

HostKey /etc/ssh/ssh_host_rsa_key
HostKey /etc/ssh/ssh_host_ecdsa_key
HostKey /etc/ssh/ssh_host_ed25519_key

PermitRootLogin yes
PasswordAuthentication yes
PermitEmptyPasswords yes

  • service ssh restart
