Our Next User Summit to be Held on September 15 in Downtown Manhattan

Last year marked the arrival of the very first Xen Project User Summit.  This year, we are aiming to draw over 100 people to the Lighthouse Executive Conference Center in the heart of New York City to discuss the use of the Xen Project hypervisor.

We are actively looking for people who are willing to talk about:

RDO Havana Neutron Namespaces Troubleshooting for OVS&VLAN(GRE) Config

The  OpenStack Networking components are deployed on the Controller, Compute, and Network nodes in the following configuration:
In case of Two Node Development Cluster :-
Controller node: hosts the Neutron server service, which provides the networking API and communicates with and tracks the agents.
DHCP agent: spawns and controls dnsmasq processes to provide leases to instances. This agent also spawns neutron-ns-metadata-proxy processes as part of the metadata system.

IVI system sandboxing: The next frontier for in-vehicle upgrades

Alex Agizim, VP and CTO of Embedded Systems at GlobalLogic, had the opportunity to speak at Linux Foundation Collaboration Summit 2014, in Napa, about their use of the Xen Project Hypervisor for building OSS-based IVI (In-Vehicle Infotainment) systems.

Virtualization on ARM with Xen

This is a repost of a tutorial published initially on – Thank you to Andrew Wafaa for allowing us to repost.

With ARM entering the server space, a key technology in play in this segment is Virtualization. Virtualization is not a tool solely for servers and the data center, it is also used in the embedded space in segments like automotive and it is also starting to be used in mobile.
