My test case in the description is actually incorrect as an armhf cloud
image would need to be built with the version of livecd-rootfs from
-proposed. Phil Roche did build those images for me though and I
downloaded them from https://private-
fileshare.canonical.com/~philroche/LP-2036730/. After which I booted the
image with the following command (also seen in a previous comment of
mine).

 $ qemu-system-aarch64 \
-machine virt -m 4G -smp 4 -nographic \
-object rng-random,filename=/dev/urandom,id=rng0 \
-device virtio-rng-pci,rng=rng0,id=rng-device0 \
-drive if=pflash,format=raw,unit=0,read-only=on,file=/usr/share/AAVMF/AAVMF32_CODE.fd \
-device virtio-net-pci,netdev=eth0 \
-netdev user,id=eth0,hostfwd=tcp::8022-:22 \
-drive file=lunar-server-cloudimg-armhf.img,if=virtio,format=qcow2 

With the current daily lunar-server-cloudimg-armhf.img file I never saw
any output when booting the image other than:

EFI stub: Booting Linux Kernel...
EFI stub: Entering in SVC mode with MMU enabled
EFI stub: Using DTB from configuration table
EFI stub: Exiting boot services...

With the image build with the version of livecd-rootfs from -proposed I
saw the full boot sequence and was presented with a log-in prompt.

Ubuntu 23.04 ubuntu ttyAMA0

So I'm setting this to verification-done for Lunar.

Bug description:
  Description
  -----------
  The cloud images produced by livecd-rootfs do not properly configure the tty for armhf and subsequently the terminal output is not available.

  Test Case
  ---------
  1) Run `autopkgtest-buildvm-ubuntu-cloud -v --arch armhf --release mantic` substituting the release name as appropriate
  2) Observe the last console message `EFI stub: Exiting boot services...`

  With a cloud image build with the livecd-rootfs version in -proposed
  you'll see much more output from `autopkgtest-buildvm-ubuntu-cloud`
  including cloud-init configuring the system.

  Regression Potential
  --------------------
  The serial console is being set to ttyS0 differently that it was for architectures other than arm64 or armhf. However, this has been in place in noble for an extended period of time and has not cause any regressions for those architectures.

  Original Description
  --------------------
  On an arm64 as well as on amd64 I saw this behavior:

  $ autopkgtest-buildvm-ubuntu-cloud -v --arch armhf --release mantic
  $ autopkgtest -U --apt-pocket=proposed -a armhf -s *.dsc -- qemu autopkgtest-mantic-armhf.img
  autopkgtest [13:18:32]: starting date and time: 2023-09-20 13:18:32+0200
  autopkgtest [13:18:32]: version 5.28ubuntu1
  autopkgtest [13:18:32]: host mcbin; command line: /usr/bin/autopkgtest -U --apt-pocket=proposed -a armhf -s forensics-all_3.47.dsc -- qemu autopkgtest-mantic-armhf.img
  qemu-system-aarch64: terminating on signal 15 from pid 3520 (/usr/bin/python3)
  <VirtSubproc>: failure: timed out waiting for 'login prompt on serial console'
  autopkgtest [13:19:33]: ERROR: testbed failure: unexpected eof from the testbed

  When trying to boot into the image on an arm64 system with

  qemu-system-aarch64 \
  -machine virt -accel kvm -m 4G -smp 4 -cpu host,aarch64=off -nographic \
  -object rng-random,filename=/dev/urandom,id=rng0 \
  -device virtio-rng-pci,rng=rng0,id=rng-device0 \
  -drive if=pflash,format=raw,unit=0,read-only=on,file=/usr/share/AAVMF/AAVMF32_CODE.fd \
  -device virtio-net-pci,netdev=eth0 \
  -netdev user,id=eth0,hostfwd=tcp::8022-:22 \
  -drive file=autopkgtest-mantic-armhf.img,if=virtio,format=qcow2

  the last messages displayed are

  EFI stub: Booting Linux Kernel...
  EFI stub: Entering in SVC mode with MMU enabled
  EFI stub: Loaded initrd from LINUX_EFI_INITRD_MEDIA_GUID device path
  EFI stub: Using DTB from configuration table
  EFI stub: Exiting boot services...

  qemu-system-aarch64 seems to be close to idling at less than 0.5 % CPU
  load. So booting obviously stalled.
