Lago v0.39

On behalf of the Lago team, I'm pleased to announce the new release of Lago and Lago-ost-plugin:
Lago - v0.39
Lago-ost-plugin v0.41

This is the first release where we've separated Lago and lago-ost-plugin(aka ovirtlago) to different repositories, installation procedures should be the same. However, from now on the lago-ost-plugin will follow a different release cycle. It's repository can be found at [1], and docs at [2]. Note that 'lago-ost-plugin' requires Lago >= 0.39.

What's new

Lago

1. Improved Ansible inventory support. For more details see [3].
2. Lago SDK - Allows to run most CLI operations directly from Python. See [4] for the docs, and [5] for an example. This is mostly standardization of the already provided SDK.
3. Debian network support in bootstrap stage.

Lago Images

3 New images were added, please help in verifying them:

1. fc25-base
2. debian8-base
3. ubuntu16.04-base

There is a known issue with host name resolution after boot in debian, but it does not affect connectivity.

Tests/CI

1. Moved to tox to setup the virtualenv during the tests:
   • tox -e docs - builds the docs.
   • tox -e py27 - run unittests and linters.
   • tox -c tox-sdk.ini -- --stage check_patch/check_merged - to run the functional SDK tests
     for each stage(after you have installed lago - either in a nested virtualenv or from RPMs).
2. Added SDK functional tests:
   • Easy to run sanity check while developing, under tests/functional-sdk run:
     pytest -s -vvv --setup-show --stage check_patch test_sdk_sanity.py
3. Added multi-distro tests, which means prior to merging every Lago patch, we'll ensure the core images in templates.ovirt.org are functional with the new patch.
4. Added ansible functional tests on check-merged.

For the full changelog see [6].

Lago v0.37

Hi all,
On behalf of the Lago team, I'm pleased to announce Lago v0.37 is available!

What's new

General

1. Allow running arbitrary 'virt-customize' commands on template
   disks, prior to boot-up, for example:

    disks:
      - build:
        - virt-customize:
            ssh-inject: ""
            mkdir: "/tmp/some_dir"
        template_name: el7.3-base
        type: template
        name: root
        dev: vda
        format: qcow2

Will create the directory /tmp/some_dir in the template disk and
inject Lago's generated ssh-keys to the root user. For a full list of
available commands please consult virt-customize docs[1], under
'Customization options' section.

2. Allow skipping the 'bootstrap' stage(virt-sysprep) per VM, by
   defining 'bootstrap: false' under the VM definition.

Libvirt

1. Use 'host-passthrough' as the default CPU mode.
2. Allow customizing CPU definitions, with 'cpu_custom' and
   'cpu_model' parameters, see [2] for more details.
3. Automatically add DHCP leases for none management networks.
4. Auto select management network if not defined.
5. Allow defining custom DNS records in management networks.
6. Restrict DNS configurations to management networks only.
7. Enforce one management network per VM.

ovirtlago

1. Export junit XML reports generated by nose with *.junit.xml suffix.
2. Add '--with-vms' option to 'lago ovirt start'.
3. Allow defining a custom CPU <-> Cluster level mapping file.

For the full commit-log, which also includes several bug-fixes, see [3].
