Release: Karesansui 1.0

by Leave a Comment

The Karesansui project has released version 1.0 of its open source virtualization management application.

While version 1.0 only supports the Xen hypervisor, the developers plan to support KVM and other virtualization systems in the future.  Administrators can install a virtual guest OS, boot VMs, shutdown VMs, and reach the virtual console directly through a Web browser interface.

The application is licensed under the GPL and LGPL and uses open source components such as: Python, libvirt, webpy, flup, lighttpd, psycopg2, tightvncviewer, jquery, jquery.form.  The web interface also has a RESTful architecture allowing for other applications to interact with it over HTTP.

Karesansui is available to download and you can also find an installation tutorial as well.  If you are looking for screenshots, you can find them here.

Xen 3.4 Released

by Leave a Comment

Xen.org is pleased to announce the latest release of the Xen hypervisor (3.4), which is is referring to as “the open source industry standard for virtualization”.

From the blog post:

“As part of the Xen community’s commitment to continuous improvement, the new hypervisor offers significant enhancements in the following areas:

•    Xen Client Initiative (XCI) Enhancements –Xen.org continues develop industry virtualization standards for desktop and client devices. Xen 3.4 contains the initial XCI code release providing a base client hypervisor for the community to extend and improve. This new version of the Xen hypervisor expands the hardware options for the leading open source virtualization platform.

•    Reliability – Availability – Serviceability (RAS) – In addition, Xen now delivers a collection of features designed to avoid and detect system failures, provide maximum uptime by isolating system faults, and provide system failure notices to administrators to properly service the hardware/software. The combination of these services provide for a robust Xen hypervisor with fault-tolerant and back-up capabilities built-in.

•    Power Management – Xen 3.4 improves the power saving features with a host of new algorithms to better manage the processor including schedulers and timers optimized for peak power savings.”

On average, Xen.org receives more than 750 new code submissions to the source tree each month from developers across the world working on an array of solutions within the hypervisor.

AbiCloud from Abiquo

by 1 Comment

Last month Abiquo announced the release of their “abiCloud”, an open source cloud computing platform for allowing companies to create and manage large, complex IT infrastructures (virtual servers, networks, applications, storage…) in a quick, simple and scalable way.

We had a chat with Diego Mariño, Co-founder & CEO of Abiquo , he told us that
one of the key differences of AbiCloud is the the web rich interface for managing the infrastructure. He told us “You can deploy a new service just dragging and dropping a virtual machine. This version allows to deploy instances over VirtualBox, but we support VMware, KVM and Xen too.”

As their first tester had its infrastructure on Virtualbox and because its very simple to have it up and running in different architectures that’s where their first focus is at.

Today they support Xen & KVM through libvirt, and the connectors for these hypervisors will be offered during Q2. Support for VMware, is offered to hosting providers with closed modules.

Basically, Abiquo allows to companies to convert their infrastructure into a service. Other competitors in the field include the recently founded Eucalyptus, Enomaly, and sun via it’s Qlayer acquisition.

Abiquo says it has a different focus and approach , what they are offering is the ability to create private clouds for more complex infrastructures.

The have their own open API which will be released in Q3 , with no plans to support the Amazon’s API

AbiCloud is available for Download from SF.net

VMware Debuts Open Source Virtual Desktop Client

by Leave a Comment

VMware today announced the first open source client for virtual desktop infrastructure, VMware View Open Client.

VMware View enables IT organizations to safely host user desktops in the datacenter, while letting users access their personalized desktop environments from almost any device, at any time – all at a lower cost of ownership than traditional desktop environments. Now, VMware is providing VMware View Open Client for partners, enabling them to use VMware View source code to optimize their products to deliver rich, personalized virtual desktops to users. In addition, partners will be able to use the source code to help accelerate the development and delivery of solutions for enterprises to provision and manage thousands of virtual desktops simply, securely and at substantially lower operating costs.

This announcement is another important step in VMware’s vClient Initiative to deliver universal clients – desktops that follow users to any end point while providing a rich personalized experienced that is secure, cost-effective and easy for IT to manage.

VMware View Open Client is available under the GNU Lesser General Public License version 2.1 (LGPL v 2.1) and is accessible from  http://code.google.com/p/vmware-view-open-client/. Some of the features included in this release support secure tunneling using SSL, two factor authentication with RSA SecurID, Novell SUSE Linux Enterprise Thin Client Add-On RPM package and a full command line interface. Support for the source code distribution is available through the VMware View Open Client community at: http://code.google.com/p/vmware-view-open-client/.

Kemari v1.0 Released

by Leave a Comment

Last month,TAMURA Yoshiaki from the Kernel Group , OSS Computing Project at the NTT Cyber Space Labs announced the availability of Kemari on the Xen Devel mailing list.

Kemari is an open-source virtual machine synchronization mechanism for fault tolerance. It’s similar to Remus which we covered earlier.

Kemari tries to achieve a fault tolerance setup that does not
require the use of specific hardware or modification of applications.
Kemari aims to keep VMs transparently running in times of hardware
failures. It transfers the state of the primary VM to the secondary
VM when the primary VM is about to send an event to devices such as
storage and networks.
In short it is trying to real time mirroring of Virtual Machine instances.

The, source (Kemari has been released under the GPL) , documentation and different presentations including a Video running both a Linux and Windows demo are available at the Kemari Website

Kemari is listed on Xen Product Roadmap, and is asking for reviews and comments from the community.

We already mentionned Remus in earlier posts here at Virtualization.com and it seems the the Kemari and Remus project are planning to merge in order to to propose a better solution for Xen 3.4 together.

Release: Fedora 10, Including Virtualization Improvements

by Leave a Comment

The Fedora Project, a Red Hat sponsored and community-supported open source collaboration project, today announced the availability of Fedora 10, the latest version of its free open source operating system distribution. Fedora 10 features numerous technologies and continues to lay the groundwork for derivative open source distributions throughout the enterprise.

Since its inception, Fedora has adopted a leadership role in the development of open source software and continuously demonstrates its potential across the enterprise. This community of users and developers have blazed the trail in key feature development and actively forms the roadmap for open source technologies found in many platforms, including Red Hat Enterprise Linux.

Fedora 10, the tenth release in five years, features substantial virtualization improvements for remote installation and management of storage provisioning. These features will make system administration of virtual machine hosts and guests easier and more capable of automation, especially as they are integrated into Red Hat Enterprise Linux. Additionally, Fedora 10 includes NetworkManager connection sharing, allowing laptop users with an Ethernet or mobile broadband connection to provide Internet routing to others through the laptop wireless interface, for instant collaboration anywhere, anytime.
