I can reproduce this issue with a simple

  autopkgtest-buildvm-ubuntu-cloud -v -r jammy

run on a POWER machine running Jammy. The same command succeeds on my
laptop (amd64/kinetic), so this really seems to be ppc64el-specific, per
bug description. The first traceback I can see in the console log is:

I'm not convinced this is a cloud-init bug, but I added a cloud-init as
I'm not able to rule it out for now.

Title:
  autopkgtest-buildvm-ubuntu-cloud hangs on ppc64el (P9)

Status in Auto Package Testing:
  New
Status in cloud-init:
  New

Bug description:
  Trying (in different ways) to create autopkgtest VM images failed.
  e.g. with:
  sudo autopkgtest-buildvm-ubuntu-cloud -a ppc64el -r jammy -s 15G
  or:
  sudo autopkgtest-buildvm-ubuntu-cloud -r jammy -v --cloud-image-url http://cloud-images.ubuntu.com/daily/server -s 15G -a ppc64el
  or just native on ppc64el:
  sudo autopkgtest-buildvm-ubuntu-cloud -v

  Things look generally pretty promising, but eventually the image hangs / does not complete and the latest console messages are:
  ...
  [  OK  ] Finished Record Runlevel Change in UTMP.
  [FAILED] Failed to start Execute cloud user/final scripts.
  See 'systemctl status cloud-final.service' for details.
  [  OK  ] Reached target Cloud-init target.

  or:
  [  387.904399] cloud-init[1234]: Cloud-init v. 22.2-0ubuntu1~22.04.3 finished at Tue, 23 Aug 2022 12:23:09 +0000. Datasource DataSourceNoCloud [seed=/dev/vdb][dsmode=net].  Up 387.81 seconds
  [FAILED] Failed to start Execute cloud user/final scripts.
  See 'systemctl status cloud-final.service' for details.
  [  OK  ] Reached target Cloud-init target.

  Due to this it's currently not possible to use autopkgtests with VMs
  on ppc64el.

  (Might also be a cloud-init issue.)
