[SRU] WALinuxAgent/Cloud-init failure for Snappy

[Ben Howard]

SRU Justification

[IMPACT] Ubuntu Snappy only boots about ~40% of the time on Azure. This is caused by Cloud-init's reliance on WALinuxAgent to handle some of the boot-time provisioning

[FIX] Backport of the 15.10 Datasource to 15.04.

[Test Case 1] Upgrade from proposed
1. Install cloud-init from proposed
2. Change the hostname via /etc/hostname
3. Reboot
4. Capture VM
5. Boot captured VM
6. Confirm that Cloud-init used WALinuxAgent

[Test Case 2] Disable WALinuxagent provisioning and use cloud-init exclusively
1. Install cloud-init from proposed
2. Run:
$ cat > /etc/cloud/cloud.cfg.d/99-azure-ds.cfg <<EOF
datasource:
  Azure:
    agent_command: "__builtin__"
EOF

$ cat > /etc/default/walinuxagent <<EOF
# Disabled
WALINUXAGENT_ENABLED=0
EOF
3. Shutdown and capture VM
4. Launch captured VM
5. Confirm that waagent is not running
6. Check /var/lib/cloud-init.log for errors

[Test Case 3] New Image Launch
1. Build an Azure image from -proposed, with settings in test case 2
2. Boot image
3. Confirm that the image comes up

[Regression Potential] As this is a backport of the 15.10 Datasource, there is a medium regression potential. The 15.10 Datasource fixes a number of Azure provisioning bugs and is thus desirable.

The updated Datasource includes additional automated testing to confirm code quality.

Hello Ben, or anyone else affected,

Accepted cloud-init into vivid-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/cloud-init/0.7.7~bzr1091-0ubuntu2 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 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, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

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

Marking as verification done. Test cases complete.

This bug was fixed in the package cloud-init - 0.7.7~bzr1091-0ubuntu2

---------------
cloud-init (0.7.7~bzr1091-0ubuntu2) vivid; urgency=medium

  * Backport of 15.10 Azure Datasource to fix various issues:
    - Azure Datasource writes user password in plain text (LP: #1458052).
    - Hostname not preserved across Azure reboots (LP: #1375252).
    - Allow provisioning of Ubuntu Snappy w/out WALinuxAgent (LP: #1448885).
