bvirt: default network conflicts (not anymore), by Kashyap Chamarthy

Increasingly there’s a need for libvirt networking to work inside a virtual machine that is already running on the default network (192.168.122.0/24). The immediate practical case where this comes up is while testing nested virtualization.

Red Hat welcomes Oracle to the RDO community! by Rich Bowen

It was with surprise and pleasure that we learned of Oracle’s decision to base their commercial OpenStack offering on the community-supported RDO distribution of OpenStack.

It was with surprise and pleasure that we learned of Oracle’s decision to base their commercial OpenStack offering on the community-supported RDO distribution of OpenStack. (See their packstack-based deployment instructions here.) We are always happy to see people use our distribution, on which we encourage people to build proof of concept or test deployments of OpenStack on CentOS, Fedora, and Red Hat Enterprise Linux as well as those other derivative distros.

If you experience difficulties with Oracle OpenStack, we encourage you to drop by the #RDO channel on Freenode for help in getting it working. The more people using OpenStack, the better, right?

Of course, when you are ready to move to production, we encourage you to move to our production-hardened, ecosystem-supported, enterprise-ready Red Hat Enterprise Linux OpenStack Platform, to ensure the best OpenStack experience possible.

And, Oracle, we encourage you to send your fixes back upstream. We look forward to your participation in the RDO community.

What’s Coming in OpenStack Networking for Juno Release, by Nir Yechiel

Neutron, historically known as Quantum, is the OpenStack project focused on delivering networking as a service. As the Juno development cycle ramps up, now is a good time to review some of the key changes we saw in Neutron during this exciting cycle and have a look at what is coming up in the next upstream major release which is set to debut in October.

Visualizing Heat stacks

I spent some time today learning about Heat autoscaling groups, which are incredibly nifty but a little opaque from the Heat command line, since commands such as heat resource-list don’t recurse into nested stacks. It is possible to introspect these resources (you can pass the physical resource id of a nested stack to heat resource-list, for example)…

OpenStack Resources for the vAdmin

Across many enterprise organizations, IT is driving innovation that allows companies to be more agile and gain a competitive edge. These are exciting times for the Vadmins who are at the center of this change. This innovation starts with bridging the gap between traditional virtualization workloads and cloud-enabled workloads based on OpenStack.

Red Hat Enterprise Virtualization 3.4.1 Released

Keystone is not an authentication service, by Nathan Kinder

In my previous post about security related updates that are coming in Juno, I mentioned that Keystone itself is a poor identity management solution. I feel that this is a topic that deserves a more thorough discussion.

Getting Service Users out of LDAP, by Adam Young

Most people cannot write to the LDAP servers except to manage their own data. Thus, OpenStack requiring the Service users in LDAP is a burden that many IT organizations cannot assume. In Juno we have support for Multiple backends for domains.
