Building OpenStack for Debian/CentOS

● OpenStack Packaging for AArch64 (LEG 188)

● Linaro overlay RP 16.06 - Mitaka○ OpenStack packages available:

■ Debian: http://bit.ly/LEG-PKG-Debian■ CentOS: http://bit.ly/LEG-PKG-Centos

● Newton OpenStack (planned for RP 16.12)○ Ceph: http://repo.linaro.org/ubuntu/leg-ceph ○ Preparing OpenStack components for deploying (LEG 196)

● Images for AArch64 OpenStack○ CirrOS Image: http://bit.ly/LEG-DC-Cirros○ Linaro RP Debian Image: http://bit.ly/LEG-DC-Debian○ Linaro RP CentOS image: http://bit.ly/LEG-DC-Centos○ Upstream Fedora, CentOS and CoreOS new images coming soon

Ceph - Storage● Block storage (RBD) and Object storage (OSD) have been

validated on AArch64○ Verified by Ceph Unit Tests and by running on the Developer Cloud

● Ceph RBD integration with OpenStack is finished on

AArch64○ Use Ceph as Cinder backend to provide volume service

● Ceph OSD integration with OpenStack is ongoing on

AArch64○ Most features are verified

● Ceph performance testing is ongoing on AArch64○ Ceph cluster performance on AArch64 compared with X86

Test Setup● DevStack is used for Nova and other OpenStack components development.

● Most use cases can be deployed by running all OpenStack services in one host.

● Multiple nodes deployment is also required to simulate real life cases.
