Here's what RDO enthusiasts have been writing about in the last week:

Deploying an OpenStack undercloud/overcloud on a single server from my
laptop with Ansible. by Harry Rybacki

During the summer of 2014 I worked on the OpenStack Keystone component
while interning at Red Hat. Fast forward to the end of October 2015 and
I once again find myself working on OpenStack for Red Hat — this time on
the RDO Continuous Integration (CI) team. Since re-joining Red Hat I’ve
developed a whole new level of respect not only for the wide breadth of
knowledge required to work on this team but for deploying OpenStack in

Ceilometer Polling Performance Improvement, by Julien Danjou

During the OpenStack summit of May 2015 in Vancouver, the OpenStack
Telemetry community team ran a session for operators to provide
feedback. One of the main issues operators relayed was the polling that
Ceilometer was running on Nova to gather instance information. It had a
highly negative impact on the Nova API CPU usage, as it retrieves all
the information about instances on regular intervals.

AIO RDO Liberty && several external networks VLAN provider setup by
Boris Derzhavets

Post below is addressing the question when AIO RDO Liberty Node has to
have external networks of VLAN type with predefined vlan tags. Straight
forward packstack –allinone install doesn't allow to achieve desired
network configuration. External network provider of vlan type appears to
be required. In particular case, office networks vlan
tagged (157) , vlan tagged (172), vlan tagged
(200) already exists when RDO install is running. If demo_provision was
"y" , then delete router1 and created external network of VXLAN type

Caching in Horizon with Redis by Matthias Runge

Redis is a in-memory data structure store, which can be used as cache

–enablerepo=rawhide install python-django-redis.

Red Hat Cloud Infrastructure Cited as a Leader Among Private Cloud
Software Suites by Independent Research Firm by Gordon Tillmore

The Forrester report states that Red Hat “leads the evaluation with its
powerful portal, top governance capabilities, and a strategy built
around integration, open source, and interoperability. Rather than
trying to build a custom approach for completing functions around
operations, governance, or automation, Red Hat provides a very
composable package by leveraging a mix of market standards and open
source in addition to its own development.”

Disable "Resource Usage"-dashboard in Horizon by Matthias Runge

When using Horizon as Admin user, you probably saw the metering
dashboard, also known as "Resource Usage". It internally uses
Ceilometer; Ceilometer continuously collects data from configured data
sources. In a cloud environment, this can quickly grow enormously. When
someone visits the metering dashboard in Horizon, Ceilometer then will
accumulate requested data on the fly.
