# Ubuntu 22.04 LTS

Canonical CloudStack KVM template rebuilt and validated on 2026-08-10 from the official Ubuntu 22.04 release KVM cloud image.

## Artifact

- File: `ubuntu-22.04.qcow2`
- Source image: `ubuntu-22.04-server-cloudimg-amd64-disk-kvm.img`
- Source URL: https://cloud-images.ubuntu.com/releases/server/jammy/release/
- Format: QCOW2, sparse and uncompressed (`0.00%` compressed clusters)
- Architecture: x86_64
- Virtual disk: 30 GiB (32212254720 bytes)
- Physical file size: 2.18 GiB (2336882688 bytes)
- SHA-256: `952c5f4f3c0339b1308d02269c4b283ac2cfd087d53dbf59a4f7843e1864e5bd`
- Mirror URL: https://cloud-mirrors.noc.sh/ubuntu-22.04/ubuntu-22.04.qcow2
- CloudStack template UUID: `e4211572-7100-4a57-a225-a363ea09b099`
- CloudStack state: Ready / Download Complete

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; the validated guest contains 598 packages. Installer state, caches, logs, machine identity and SSH host keys were sealed so that each deployed VM regenerates its own identity.

## CloudStack registration

- Hypervisor: KVM
- Format: QCOW2
- OS type: Ubuntu 22.04 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-22.04.qcow2
qemu-img check ubuntu-22.04.qcow2
qemu-img info ubuntu-22.04.qcow2
```

Expected SHA-256:

```text
952c5f4f3c0339b1308d02269c4b283ac2cfd087d53dbf59a4f7843e1864e5bd  ubuntu-22.04.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 26.1 used the CloudStack data source with `errors: []` and no recoverable warnings; networking, password-only root SSH, hostname assignment and QEMU guest agent were validated. No failed systemd units remained.

## Lifecycle note

This is the only retained Ubuntu 22.04 artifact. The superseded ISO-built template and the unmodified cloud-image control were removed after this cloud-image-based template passed acceptance.
