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.
