Rackspace Cloud Servers Adds Four New Linux Operating System Distributions


Rackspace has added four new Linux operating system distributions for Cloud Servers, giving the Linux community in the cloud more choice. We have added Fedora 17, CentOS 5.8, CentOS 6.2 and Ubuntu 12.04. These are available in addition to our variety of popular 64-bit Linux distributions.

All four images are available for both Cloud Servers and Cloud Servers powered by OpenStack. Both versions enable customers to create, view, update and delete Cloud Servers, as well as create on-demand images.

The newest generation of Rackspace Cloud Servers is powered by OpenStackā„¢ and provides the reliability and on-demand scalability customers need, while eliminating worries about vendor lock-in. Customers have access to a new, easy-to-use control panel and a powerful new API- – and of course, everything is backed by our industry leading Fanatical Support.

Rackspace is still accepting applications to a Limited Availability Program for Cloud Servers powered by OpenStack. A limited number of customers will be accepted into the program on a first-come, first-served basis. Sign up here:

To our Cloud Servers customers, thank you for entrusting Rackspace with your business. As always, we invite you to provide feedback here.

    I run CentOS 6.0 on a Rackspace Cloud Server. Is there a way to do an in place upgrade to CentOS 6.2 without breaking anything (of course with no guarantees, just a general ‘probably ok’)? Or must the server be recreated?

    • Jeremy Collake

      I’m also curious why CentOS 5.8 was ‘added’. You added an older distro? Did people desire it for some reason?

    Thank you for the comments, here are some answers:

    1. To your first comment, here is some information on how to get upgraded: “Yes, within the slice they can do whatever they want with their data, and CentOS does provide point upgrades to their system. Basically if they have regular updates turned on, they’ll be upgraded automatically to 6.1, 6.2, etc…”

    2. To your second comment, we deploy both CentOS 5.x and 6.x versions because some customers have standardized on version 5 and dont necessarily want to update to version 6. For those who want the latest and greatest, we will deploy the latest updates as development resources allow.

    With regards,

    Is there any reason that you don’t support 32-bit versions? It’s a blocker for us to migrate from Linode.

    It is pretty common to use a 32-bit OS for application servers, as it uses significantly less memory – for instance, a vanilla Rails + Unicorn process takes 200MB on 64bit vs 60MB on 32bit.

    We use 64-bit flavors for databases, but other than that, using 32-bit on smaller instances yields better results on all fronts.
