Sure, however virt-install currently is not the best way to experience any
release of Ubuntu. That's why MAAS, Canonical Distribution of Openstack,
LXD, Multipass and all public & private clouds that provide Ubuntu consume
and use cloud images, providing a superior experience & configurability
than all other distributions mentioned. The above products cater from
Multipass "give me a quick VM", to manage a "small cloud" / "very bit
cloud".

And virt-install using d-i or iso, instead of qcow2 images (with or without
unpacked kernel) as inputs for any release of Ubuntu, on any architecture
is suboptimal. virt-install should be using cloud images for Ubuntu 12.04
LTS (precise and up). Just like Multipass, lxd-kvm, maas KVM pods,
OpenStack. Many other distributions also provide cloud-init enabled images.
There was GSOC project to get "cloud-init" support but that only landed on
a branch, and hasn't made it into release.

It seems to me that virt-install pre-dates the times of distributions
providing preinstalled cloud-init enabled qcow2 images. Hence so much
automation grew around the suboptimal inputs. Cloud-images is not an
ubuntu-only feature.

Given that the d-i paths changed, and I can't make them compatible enough,
I will reopen the virt-install task to fix path detection in virt-install,
at a wishlist priority. I'll open a separate feature request to support
cloud-images in virt-install & forward it upstream, also at wishlist
priority.

Title:
  [Ubuntu 20.04] virt-install fails to detect path after images folder
  name has changed

Status in Ubuntu CD Images:
  Opinion
Status in Ubuntu on IBM z Systems:
  Won't Fix
Status in debian-installer package in Ubuntu:
  Won't Fix
Status in virt-manager package in Ubuntu:
  Invalid

Bug description:
  Installer version: Latest
  https://ports.ubuntu.com/ubuntu-ports/dists/focal/main/installer-s390x

  Description/Reproduction:
  Start virt-install with the following options:

  virt-install \
  --name ubuntu20-guest1 \
  --memory 4096 \
  --vcpus 4 \
  --disk "size=4" \
  --location http://ports.ubuntu.com/ubuntu-ports/dists/focal/main/installer-s390x \
  --network "network=default" 

  Error:
  ERROR    Error validating install location: Could not find an installable distribution at 'http://ports.ubuntu.com/ubuntu-ports/dists/focal/main/installer-s390x'

  The location must be the root directory of an install tree.
  See virt-install man page for various distro examples.

  
  Looking at previous releases I would guess it expects an "images" directory instead of the new "classic-images" directory. I'm aware of the workaround to specify kernel/initramfs directly but that shouldn't be a solution.
