LCA14-505: OpenStack cookbook

2. • What’s the current status of openstack testing using
components coming out of Linaro’s CI
• Also what is tested in LAVA
• CARD-871 - Openstack “cookbook” testing
• What, why, how
• Anything missing from that card?
• Future steps - what else should we be doing?
Agenda

3. • Deploying using Devstack on Midway running Saucy
• Dependent on libvirt and qemu with virt support (both upstream for a
while now)
• Using Linaro CI-built packages available from repo.linaro.org
• Modifications to Nova to support virt (merged upstream 18-Feb)
• Slightly-modified Devstack (minor fixes only): https://git.linaro.
org/people/clark.laughlin/devstack.git
• Running Devstack Exercises
• Running Tempest (2108 tests run, 21 failures)
• Documentation:
• Running a virt guest using libvirt: https://wiki.linaro.
org/OpenStack/LibvirtAndMachvirt
• Deploying Openstack using Devstack: https://wiki.linaro.

What Works

4. • Running the tests in LAVA
• mostly functional, still tracking down differences between running on
Saucy and running on Linaro builds
• Attaching a volume to a running instance (needs hotplug
support)
• work to be done
• Rebooting / cleanly powering down a running instance
• work to be done
• VNC console
• no plans to support
• Documentating here: https://wiki.linaro.

What Does Not Work (Yet)

5. • Questions:
• Anything missing?
• Where to run all the components?
• All on ARM, or split between ARM and x86 hardware / VMs?
• Test in phases?
• CARD-871 is about KVM - what about XEN?
CARD-871: Openstack “cookbook” testing

6. Backup - CARD-871 use cases
Use case family Use case
Configuration and
deployment
● Install openstack components
● Deploy openstack using MAAS and juju
● Increase openstack compute capacity using juju
● Configure load balancing
Administration ● Add or modify user accounts
● Manage security groups
● Create and manage SSH keypairs
● Use public cloud images
Openstack identity
service
● Install and configure keystone
● Configure openstack tenants
● Configure openstack roles
● Configure openstack nova to work with openstack identity service
Openstack storage ● Create containers, upload objects, list containers and objects, delete containers
and objects
● Download objects
● Ensure that usage statistics are working
Openstack image
service
● Configure openstack image service with openstack storage
● Manage images (ie using glance): upload, index, delete, turn private images to
public

7. Backup - CARD-871 use cases
Use case family Use case
Nova volumes
(persistent storage)
Confirm that creating, attaching and detaching volumes works in nova
Openstack networking ● Flat networking with DHCP
● Configure VLAN manager networking
● Configure per project (tenant) IP ranges
● Fixed networks to tenants: assigning, modifying
● Associate and disassociate floating IPs to instances (ie via nova-manage)

8. The Devstack exercises perform testing of the following
operations:
• Boot instance
• Boot instance from volume
• Create / view / delete volume
• Attach / detach volume*
• Create, modify, delete host aggregates
• CLI authentication
• Create, modify, delete security group
• Create, modify, delete security group rules
• Create Swift container, add & list contents, delete
container
* does not work yet
