openSUSE packages core python2 modules like the xml one in a separate package called python-xml. Similarly, python3 contains the base modules in python3-base and the xml one in python3. As such it's best to ensure that both python-xml and python3 are installed similar to I5cd5d1127ae62d6753c2ace44965179c5400bb9a Also, update bindep.txt to include python3-devel and python-xml for SUSE distros. This is supposed to fix python3 related failures on openSUSE jobs such as the following one: 2017-06-28 13:00:47.628446 | + virtualenv -p python3 env 2017-06-28 13:00:47.926042 | Using base prefix '/usr' 2017-06-28 13:00:47.926098 | New python executable in /home/jenkins/env/bin/python3 2017-06-28 13:00:47.926117 | Also creating executable in /home/jenkins/env/bin/python 2017-06-28 13:00:47.926144 | Please make sure you remove any previous custom paths from your /home/jenkins/.pydistutils.cfg file. 2017-06-28 13:00:48.303569 | Installing setuptools, pip, wheel... 2017-06-28 13:00:48.303705 | Complete output from command /home/jenkins/env/bin/python3 - setuptools pip wheel: 2017-06-28 13:00:48.303733 | Traceback (most recent call last): 2017-06-28 13:00:48.303748 | File "<stdin>", line 7, in <module> 2017-06-28 13:00:48.303782 | File "/usr/lib/python2.7/site-packages/virtualenv_support/pip-9.0.1-py2.py3-none-any.whl/pip/__init__.py", line 26, in <module> 2017-06-28 13:00:48.303816 | File "/usr/lib/python2.7/site-packages/virtualenv_support/pip-9.0.1-py2.py3-none-any.whl/pip/utils/__init__.py", line 27, in <module> 2017-06-28 13:00:48.303868 | File "/usr/lib/python2.7/site-packages/virtualenv_support/pip-9.0.1-py2.py3-none-any.whl/pip/_vendor/pkg_resources/__init__.py", line 35, in <module> 2017-06-28 13:00:48.303904 | File "/usr/lib64/python3.4/plistlib.py", line 65, in <module> 2017-06-28 13:00:48.303920 | from xml.parsers.expat import ParserCreate 2017-06-28 13:00:48.303932 | ImportError: No module named 'xml' Change-Id: I32899793a78464e25aec0e213eee9c65bd915a51 |

Using diskimage-builder to build devstack-gate nodes
In addition to being able to just download and consume images that are the same as what run devstack-gate, it's easy to make your own for local dev or testing - or just for fun.
Install diskimage-builder
Install the dependencies:
sudo apt-get install kpartx qemu-utils curl python-yaml debootstrap
Install diskimage-builder:
sudo -H pip install diskimage-builder
Build an image
Building an image is simple, we have a script!
bash tools/build-image.sh
See the script for environment variables to set distribution, etc. By default it builds an ubuntu-minimal based image. You should be left with a .qcow2 image file of your selected distribution.
Infra uses the -minimal build type for building Ubuntu/CentOS/Fedora. For example: ubuntu-minimal.
It is a good idea to set TMP_DIR
to somewhere with
plenty of space to avoid the disappointment of a full-disk mid-way
through the script run.
While testing, consider exporting DIB_OFFLINE=true, to skip updating the cache.
Mounting the image
If you would like to examine the contents of the image, you can mount it on a loopback device using qemu-nbd.
sudo apt-get install qemu-utils
sudo modprobe nbd max_part=16
sudo mkdir -p /tmp/newimage
sudo qemu-nbd -c /dev/nbd1 /path/to/devstack-gate-precise.qcow2
sudo mount /dev/nbd1p1 /tmp/newimage
or use the scripts
sudo apt-get install qemu-utils
sudo modprobe nbd max_part=16
sudo tools/mount-image.sh devstack-gate-precise.qcow2
sudo tools/umount-image.sh
Other things
It's a qcow2 image, so you can do tons of things with it. You can upload it to glance, you can boot it using kvm, and you can even copy it to a cloud server, replace the contents of the server with it and kexec the new kernel.
