For several years now, the oVirt project is leveraging KVM and relevant technologies (ksm, etc) in data center virtualizations. Being a mature and feature reach, oVirt takes another step forward with introducing NUMA architecture support which will allow better utilization of hypervisors in advanced virtual data centres. Different NUMA implementations and insights on use cases will allow participants to gain more knowledge on how to optimize their existing hypervisors in the virt world.

Starting the latest release of the oVirt project, NUMA architecture is supported. This presentation will cover general NUMA architecture concepts, as well as review recent oVirt improvements to support NUMA.

The first part will provide an introduction to Non Uniform Memory Access and its importance for better utilization of current hardware. The differences between NUMA implementations in various Linux kernels (numad VS autonuma) should provide insights on how NUMA is implemented to participants of this presentation.

The second part of this session we will present support of various NUMA modes with insights for various flows and use cases. participants will hear about virtual NUMA options available today, which are quite advanced in the virt world.

For several years now, oVirt has managed Virtual Machines. Then came the question: can you run oVirt inside a VM, which in turn will be managed by the hosted oVirt? In this session we'll look at the intricacies of an egg hosting it's parent chicken. We'll cover the various aspects starting with installation, going through standard operations, and ending with high-availability for the hosted engine. Participants will be able to get insights of this unique setup, which will save them a physical server (or even two) while allowing standard flows to run the same way they did in the past years.

GlusterFS is a distributed file system that can scale to several PetaBytes. oVirt is a management platform for Kernel based Virtual Machine (KVM) and can be used to manage GlusterFS as well. This talk will focus on GlusterFS integration with oVirt.

This talk will focus on GlusterFS integration with oVirt. GlusterFS and KVM virtualization users and developers will be able to get more information on GlusterFS concepts, enabling it in oVirt for virtualization, a short overview of oVirt and VDSM architecture including VDSM storage concepts. This will be followed by GlusterFS as a VDSM Storage Domain, as well as GlusterFS domain support in oVirt engine.

The oVirt Project is an open virtualization project providing a feature-rich server and desktop virtualization management platform with advanced capabilities for hosts and guests, including high availability, live migration, storage management, system scheduler, and more. oVirt provides an integration point for several open source virtualization technologies, including kvm, libvirt, spice and oVirt node.

The project has an open governance model, and initial board has members from IBM, Cisco, Netapp, Red Hat and SUSE. The session will provide an intro to the project components and features.

Maintaining QoS in cloud computing requires host-level monitoring and policy enforcement. In order to be able to scale up large setups, a host-level agent is needed to supervise and dynamically handle the VMs resource consumption based on the SLA policy. In this session we'll look at MoM, and get a in-dept view of it's integration with VDSM and functionalities. Participants will be able to get insights on memory overcommitment in hypervisors and the way memory balloon device is being used to achieve overcommitment.
