What's New in Rackspace Private Cloud Software v 3.0

Rackspace Private Cloud Software v 3.0 has the following new features and documentation.

Rackspace Private Cloud Software with OpenCenter™

Rackspace Private Cloud Software v 3.0 introduces OpenCenter, a deployment and management framework that enables users to quickly deploy an OpenStack cluster configured according to the recommendations of Rackspace OpenStack specialists. OpenCenter uses Chef to deploy Rackspace Private Cloud Software cookbooks.

OpenCenter enables cloud administrators to manage the architecture of their OpenStack private cloud through a GUI dashboard, command line interface (CLI), or API. With OpenCenter, you can perform the following tasks:

  • Create a Chef server that will manage multiple OpenStack nodes.
  • Deploy controller nodes and hypervisors directly to bare metal servers.
  • Deploy and manage an OpenStack cluster in an environment.
  • Enable high availability.

You can deploy Rackspace Private Cloud Software on Ubuntu 12.04, CentOS 6.3, or RHEL 6.3 or 6.4. The installation is performed by means of RPM and Debian packages.

OpenCenter has three components:

  • OpenCenter Server: The server manages the OpenCenter environment.
  • OpenCenter Agent: The agent is installed on each node that will be managed by OpenCenter.
  • OpenCenter UI: The UI on any device through which you want to manage the OpenCenter environment.

The following user documentation is available for Rackspace Private Cloud Software via the Rackspace Knowledge Center:

  • Rackspace Private Cloud Software Getting Started Guide
  • Rackspace Private Cloud Software API and CLI Guide
  • Rackspace Private Cloud Software: OpenStack Object Storage
  • Rackspace Private Cloud Software: OpenStack Block Storage
  • Rackspace Private Cloud Software: Virtual Machine Block Migration Guide
  • Rackspace Private Cloud Software: sosreport Guide

Note: Rackspace recommends that you run OpenCenter behind a firewall, as it is not considered secure at this time.

High Availability

Rackspace Private Cloud Software has the ability to implement support for high availability for all Nova service components and APIs, Cinder, and Keystone, and Glance, as well as the scheduler, rabbitmq, and mysql. HA functionality is powered by Keepalived and HAProxy.

High Availability is implemented when you create two Controller nodes in a Nova cluster. When the second node is created, it discovers the IP address of the first node and begins replication; in turn, when Chef client runs on the first node, it discovers the second and begins replication.

Known Issues

The following known issues have been identified in Rackspace Private Cloud Software v. 3.0.

Intermittent collectd Issues

Users may experience collectd failures with monitoring processes or after performing a failover to a standby node. In the event of a failure, kill any active collectd process and run chef-client on the node again.

Intermittent GUI Delays

Occasionally, dragging a node into the Infrastructure container may appear to briefly fail, with the node appearing to return to the Available Nodes container. OpenCenter is actually in the process of creating the adventure. If you wait briefly, the node will appear in the Infrastructure container.

Horizon Dashboard Admin Cookie Issues

Cookie issues associated with the admin user may cause the user to randomly switch between the demo project and the admin project. You may also experience connectivity issues if you do not log out correctly. This is related to a known issue in OpenStack.

To work around this issue, do not create instances when logged in as the admin user. To create new instances, use the demo project or a new project as a non-admin user.

VNC and HA Infrastructure

In an environment with HA Infrastructure nodes, instance VNC in the Horizon dashboard will not work.

Ubuntu and Kernel Version Compatibility with KVM

If you are installing Rackspace Private Cloud Software on devices with Ubuntu and KVM, you should use a base install of Ubuntu 12.04 or 12.04.1 where the latest available kernel version is 3.2.n (as of March 2013).

You should avoid a base install of Ubuntu where the default kernel version is greater than 3.2.n, which are currently point releases 12.04.2 and later. You can safely upgrade your base install of 12.04 or 12.04.1 to the latest point release as long as the kernel version remains 3.2.n. This is related to a known issue in OpenStack.

Resolved Issues

The following issues have been resolved in Rackspace Private Cloud Software v 3.0.

Rackspace Logo in Horizon Dashboard

Errors previously generated by clicking on the Rackspace logo in the Rackspace custom Horizon dashboard no longer occur.
