9 tips to properly configure your OpenStack Instance

In OpenStack jargon, an Instance is a Virtual Machine, the guest workload. It boots from an operating system image, and it is configured with a certain amount of CPU, RAM and disk space, amongst other parameters such as networking or security settings.

In this blog post kindly contributed by Marko Myllynen we’ll explore nine configuration and optimization options that will help you achieve the required performance, reliability and security that you need for your workloads.

Some of the optimizations can be done inside a guest regardless of what has the OpenStack Cloud Administrator enabled in your cloud. However, more advanced options require prior enablement and, possibly, special host capabilities. This means many of the options described here will depend on how the Administrator configured the cloud, or may not be available for some tenants as they are reserved for certain groups. More information about this subject can be found on the Red Hat Documentation Portal and its comprehensive guide on OpenStack Image Service. Similarly, the upstream OpenStack documentation has some extra guidelines available.

The following configurations should be evaluated for any VM running on any OpenStack environment. These changes have no side-effects and are typically safe to enable even if unused

Meet Red Hat OpenStack Platform 8

Last week we marked the general availability of our Red Hat OpenStack Platform 8 release, the latest version of Red Hat’s highly scalable IaaS platform based on the OpenStack community “Liberty” release. A co-engineered solution that integrates the proven foundation of Red Hat Enterprise Linux with Red Hat’s OpenStack technology to form a production-ready cloud platform, Red Hat OpenStack Platform is becoming a gold standard for large production OpenStack deployments. Hundreds of global production deployments and even more proof-of-concepts are underway, in the information, telecommunications, financial sectors, and large enterprises in general. Red Hat OpenStack Platform also benefits from a strong ecosystem of industry leaders for transformative network functions virtualization (NFV), software-defined networking (SDN), and more.

From Community Innovation to Enterprise Production

The path for delivering a production-ready cloud platform, starts in the open source communities that can typically innovate far more effectively than traditional R&D labs. At Red Hat we bring customers, partners, and developers into communities of purpose to solve shared problems together. Red Hat also contributes a lot of code to the OpenStack project to help drive more community development that generally results in a higher feature velocity that enterprise customers need, with a faster time to market compared to proprietary software. When useful OpenStack technology emerges, we test it, harden it, and make it more secure and reliable.

An ecosystem of integrated cloud products

In my prior post, I described how OpenStack from Red Hat frees  you to pursue your business with the peace of mind that your cloud is secure and stable. Red Hat has several products that enhance OpenStack to provide cloud management, virtualization, a developer platform, and scalable cloud storage.

Cloud Management with Red Hat CloudForms            

CloudForms contains three main components

  • Insight – Inventory, Reporting, Metrics red-hat-cloudforms-logo
  • Control – Eventing, Compliance, and State Management
  • Automate – Provisioning, Reconfiguration, Retirement, and Optimization

IBM and Red Hat Join Forces to Power Enterprise Virtualization

Adam Jollans is the Program Director  for Cross-IBM Linux and Open Virtualization Strategy
IBM Systems & Technology Group

IBM and Red Hat have been teaming up for years. Today, Red Hat and IBM are announcing a new collaboration to bring Red Hat Enterprise Virtualization to IBM’s next-generation Power Systems through Red Hat Enterprise Virtualization for Power.

A little more than a year ago, IBM announced a commitment to invest $1 billion in new Linux and open source technologies for Power Systems. IBM has delivered on that commitment with the next-generation Power Systems servers incorporating the POWER8 processor which is available for license and open for development through the OpenPOWER Foundation. Designed for Big Data, the new Power Systems can move data around very efficiently and cost-effectively. POWER8’s symmetric multi-threading provides up to 8 threads per core, enabling workloads to exploit the hardware for the highest level of performance.

Red Hat Enterprise Virtualization combines hypervisor technology with a centralized management platform for enterprise virtualization. Red Hat Enterprise Virtualization Hypervisor, built on the KVM hypervisor, inherits the performance, scalability, and ecosystem of the Red Hat Enterprise Linux kernel for virtualization. As a result, your virtual machines are powered by the same high-performance kernel that supports your most challenging Linux workloads.

Red Hat Enterprise Virtualization 3.4.1 Released

Principal Product Manager, Red Hat

I don’t often find myself getting overly excited about maintenance releases, however Red Hat Enterprise Virtualization 3.4.1 is an exception due to two key factors:

  • Preview support for Red Hat Enterprise Linux 7 as a hypervisor host
  • Support for up to 4,000 GB memory in a single virtual machine

Red Hat Enterprise Virtualization 3.4, originally introduced official guest operating system support for Red Hat Enterprise Linux (RHEL) 7. In continuing down the path of providing the latest Red Hat technologies to our customers, I am proud to announce that Red Hat Enterprise Virtualization 3.4.1 has preview support for RHEL 7 as a hypervisor.  Red Hat customers with active subscriptions will be able to take advantage of using RHEL 7 as a hypervisor either as a RHEL host, or by using our thin Red Hat Enterprise Virtualization Hypervisor image.

The Importance of Integrating Datacenter Infrastructure

By, Steve Gordon, Product Manager, Red Hat
January 23, 2014

This week heralds a refresh of Red Hat’s cloud portfolio offerings, including Red Hat Cloud Infrastructure 4.0, Red Hat Enterprise Linux OpenStack Platform 4.0, and the latest release of Red Hat’s traditional data center virtualization management platform, Red Hat Enterprise Virtualization 3.3.

We’ve put a lot of effort into our long-term cloud product strategy and the updates this week show the beginning of those efforts coming together. With this refresh, it’s clear that integration and management is the key theme behind the marketing launch activities. However, delivering real, tangible, and deployable value to our customers through Red Hat infrastructure software, is the key to success for us and this update provides you (us) the first step.

So why is integration so important in your data center? And why integrate with OpenStack? The answer lies within your own existing infrastructure, as well as your long-term plans. No, I don’t have magical powers to see your datacenter or your plans, but statistically-speaking, I can see just fine.
