Cloud Computing: A sneak peek of OpenStack Icehouse
March 24, 2014
Grazed from OpenSource. Author: Gordon Haff.
It seems like it was only yesterday that the OpenStack community found itself gathering in Hong Kong to set the design goals for the Icehouse release. As we entered March development was still progressing at a fever pitch in the lead up to the feature freeze for the release but now the dust has started to settle and we are able to start getting a real feel for what OpenStack users and operators can look forward to in the Icehouse release.
Today I’ll be giving a sneak peek to just some of the changes made in one of the two projects that made up the original OpenStack release and today is still one of the largest—showing no signs of the innovation slowing down—OpenStack Compute (Nova). OpenStack Compute is a cloud computing fabric controller, a central component of an Infrastructure as a Service (IaaS) system. It is responsible for managing the hypervisors on which virtual machine instances will ultimately run and managing the lifecycle of those virtual machine instances. This list is by no means exhaustive but highlights some key features and the rapid advances made by the contributors that make up the OpenStack community in a six month release cycle…
Libvirt/Kernel-based Virtual Machine (KVM) driver enhancements
The OpenStack User Survey results presented in Hong Kong indicated a whopping 62% of respondents are using the Libvirt/KVM hypervisor to power the compute services offered by their OpenStack clouds. The power of this combination of the Libvirt virtualization abstraction layer with the performance and security offered by the KVM hypervisor has been cemented in the datacenter and now extends to the elastic cloud. OpenStack contributors have continued in the Icehouse release to find new and innovative ways to expose the functionality provided by this combination of technologies for consumption by operators and users of elastic OpenStack clouds, delivering a number of tangible features in the abstraction layer provided by this compute driver:…
