# Ubuntu 24.04 LTS

Canonical CloudStack KVM template rebuilt and validated on 2026-08-10 from the official Ubuntu 24.04 release cloud image.

The official cloud image already included OpenSSH and cloud-init. The build added only `qemu-guest-agent` and its `liburing2` dependency, enabled CloudStack root-password provisioning, and created a fixed 1 GiB swap file. No packages were removed or generally upgraded; the validated guest contains 666 packages.

The source image shipped `cloud-init 26.1-0ubuntu1~24.04.1`, which reproduced the CloudStack first-boot DHCP regression and completed as `degraded done`. The production candidate uses the validated Noble Security version `25.1.4-0ubuntu0~24.04.1`, without an `apt` hold. Normal package updates may resume after the instance has completed its first boot.

## CloudStack registration

- Hypervisor: KVM
- Format: QCOW2
- OS type: Ubuntu 24.04 LTS
- HVM: Yes
- Password enabled: Yes
- SSH key enabled: Yes
- Public: No
- Featured: No
- Template details: none

Do not copy transient CloudStack runtime details such as `Message.ReservedCapacityFreed.Flag`.

## Verification

Run before registration:

```bash
sha256sum ubuntu-24.04.qcow2
qemu-img check ubuntu-24.04.qcow2
qemu-img info ubuntu-24.04.qcow2
```

Expected SHA-256:

```text
d74b05c6c9a8c9f423afe2b4cf99e1467bb8ed1b40f818224732433cc24df328  ubuntu-24.04.qcow2
```

The image passed Base, Pro and Ultra acceptance tests, including reboot. The root filesystem expanded to 30, 50 and 80 GiB; the fixed 1 GiB swap activated before and after reboot; cloud-init used the CloudStack datasource with `errors: []` and no recoverable warnings; networking, password-only root SSH, SSH key delivery, hostname assignment and QEMU guest agent were validated. No failed systemd units remained.

## Lifecycle note

This is the only retained Ubuntu 24.04 artifact. The superseded ISO-built template and the unmodified cloud-image control were removed after this cloud-image-based template passed acceptance.
