[Bug 2064280] Re: Hyperv desktop images no longer building in Noble

[Andreas Hasenack]

Hello Philip, or anyone else affected,

Accepted livecd-rootfs into noble-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/livecd-
rootfs/24.04.72 in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
noble to verification-done-noble. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-noble. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Title:
  Hyperv desktop images no longer building in Noble

Status in livecd-rootfs package in Ubuntu:
  Fix Released
Status in livecd-rootfs source package in Noble:
  Fix Committed

Bug description:
  We have not built Hyperv desktop images since Jammy and with the re-
  introduction of HyperV for Noble we have encountered build issues
  caused by refactoring and removals of code assumed to be redundant but
  the HyperV desktop images were actually using these code paths.

  In bbedffe6 we split the building of cloud images and non cloud to
  using an ddisk-image-uefi.binary and disk-image-uefi-non-cloud.binary
  respectively.

  In e38264ca there was a change which meant that any attempt to build
  hyperv images would result in incorrect disk size and incorrect disk
  label.

  A change in 76d79466 changed the logic of how the image size for amd64
  images were being set. This overrode the sizes set for the desktop
  images incorrectly.

  A change in 8fb21808 also removed many of the dependencies that the hyperv images require.
  This removal has been restored in this commit by adding them expliciltly in the hyperv hook.

  With Ubutnu 24.04+ cloud-init was introduced to desktop images. This
  is not required for HyperV images and can be disabled.

  This bug is to track the work to restore functioning Hyperv desktop
  image builds

  [ Impact ]

  Unable to build HyperV Desktop image.

  [ Test Plan ]

   * Successfully build image 
   * Launch through Windows HyperV manager successfully without any errors or warning. 

  [ Where problems could occur ]

   * If the image built does not launch in hyperv manager or has errors
  or warnings.

  [ Other Info ]

   * There is work required to migrate oem-config to the new
  provisioning stack but this is out of scope of this bug.
