Release: Unitrends 4.1 (Data Recovery Software)

May 13, 2009 by Robin Wauters 1 Comment

Further expanding its OS, virtualization and application support, Unitrends today announced the latest version of its data recovery software with new support for the Windows Server 2008 family and the Novell OES family of products, including Microsoft Hyper-V and Xen virtualization platforms. Unitrends Release 4.1 also includes expanded multi-appliance management and monitoring capabilities as well as enhanced support for Network Attached Storage (NAS) systems.

The new Unitrends Release 4.1 backup and recovery software offers support for more than 40 operating systems and applications. This support now includes:

·         Windows Server 2008 (including Hyper-V)

·         Exchange 2007 support on Windows Server 2008

·         SQL 2008

·         Novell OES1 and OES2 (including Xen and Groupwise 8.0)

·         MacOS X 10.5

·         Linux 64-bit

·         pSeries 6.1

The latest Unitrends release also delivers extensive context-sensitive help, increased appliance management and monitoring functionality, and new reporting flexibility. In addition, Unitrends Release 4.1 adds new appliance scalability features and supports NAS protection via CIFS and NFS protocols without a high-priced NDMP agent.

AbiCloud from Abiquo

May 5, 2009 by Kris Buytaert 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

Oracle Gets Sun xVM, Solaris Zones and Virtualbox

April 30, 2009 by Kris Buytaert 3 Comments

When Oracle announced that it will be acquiring Sun it didn’t just impact the database market. It’s not just the question of what will happen with MySQL, OpenOffice and Java. The impact on the virtualization market is big as well.

At the moment Sun has a very confusing virtualization offering: they have different flavours, different tools and, depending on which Sun representative you talk to, another technology is their next big thing. They indeed cover the 3 big areas: with Solaris Zones they have a nice OS virtualization alternative, with xVM they have a powerful Xen-based Bare metal virtualization technology based on paravirtualization, and with VirtualBox they have a Type II hypervisor ready to tackle the deskop market. A nice set of features indeed.

Oracle on the other hand was really focussing on Xen, and probably will continue to do so, so what will the future hold for Solaris Zones and VirtualBox hold.
Some people already mentioned that VirtualBox could merge up with Hosted Xen .

Now what was Oracle’s Cloud offering again? Sun already has a strategy here, and with the acquisition of Qlayer earlier this year they also have got a solid product line.

Xen just got another really strong vendor backing it’s technology, with both Citrix and Oracle behind it now. We’ll probaly find out soon.

Updates on Xen

April 16, 2009 by Kris Buytaert Leave a Comment

When you have been in this industry for a couple of years, you might think that the Virtualization industry has stopped innovating, that there are no new awesome features coming out anymore.

Obviously they aren’t coming at the same pace as 5-10 years ago anymore, we aren’t surprised anymore when people add Virtualization support for yet another CPU or publish yet another new and fresh management framework, with a cloud sauce .. But hidden far in the back corner innovation still happens, be it with much smaller and less intrusive steps than before.

So lets have a look at these small changes

First of all a project I’ve been following for a while now .. XenFS , XenFS builds on the idea that you often want to share filesystems between virtual machines on the same physical machine and that you don’t want to use NFS, Cifs or even the regular network stack to achieve this goal.

According to Mark Williamson who’s working on the project :

The major differences from a traditional network filesystem are in the implementation. XenFS is implemented as a XenLinux “split driver”, with kernel modules implementing the client and server portions. Instead of exchanging protocol messages over a network socket, XenFS exchanges requests and responses using shared memory, similar to the “device channels” used by the block and network split drivers. Beyond that, instead of copying data from the server to the client (and back) XenFS also shares the memory containing the actual file data.

XenFS has been around for a while, but KXen is actually brand new. Argumenting over the advantages and disadvantages of a TypeI vs TypeII hypervisor is now over as Xen “supports” both.

Stephen Spector announced the availability of the first public release of Hosted Xen (KXen)

According to Stephen

Xen is the leading open source Type-1 VMM, providing a fast, robust and secure virtualization platform. KXen leverages the Xen technology, extending the range of environments in which the same core engine can be used to existing desktops, laptops and allowing scenarios like run from usb stick.
Work is underway to support MacOSX as the host, as well as 64-bit versions of Windows. The windows 32-bit host code is designed such that it is easy to port to other host operating systems.

The Remus project which we covered earlier , has also released it’s initial Request for Comment code. Remus allows systems to transparently move to another physical machine in the event of a failure on the primary machine , with only seconds of downtime, while preserving the original host state such as active network connections , memory and disk state.
Being an RFC release means that it is meant to start a discussion on how it might be merged with Xen and Kemari. According to the announcement it is not by any means in shape for application to the Xen tree
But it is a giant step forward towards a better high availability solution using Virtualization.

Citrix Project Satori Sees Light Of Day

March 25, 2009 by Robin Wauters Leave a Comment

From the Xen blog:

Citrix Project Satori is the result of a collaborative agreement between XenSource and Microsoft, and was carried forward after XenSource was acquired by Citrix Systems. The base Satori components are released by Microsoft as the Linux Integration Components for Hyper-V, and provide support for paravirtualized XenLinux guests running on Hyper-V. The Linux Integration Components can be downloaded here.

The complete source code and license information (GPL version 2) on this project is now available here.

Floss Virtualization Doesn’t Care About Marketing …

March 17, 2009 by Kris Buytaert 1 Comment

It cares about Quality and Frequent code releases. The Open Source community doesn’t
wait till the week before VMWorld to announe big news, they just code along happily and when the coding is done.. they release their software.

And there was plenty of it last couple of weeks. Here’s an overview ..

  • The New Virt Manager 0.70 is out , it s featuring a Redesigned New Virtual Machine Wizard, a file browser for storage pools and volumes, there are now features to add physical device assignment (PCI,USB) for existing virtual machines.
  • Qemu, the open source processor emulator, has now a 0.10.0 Stable Branch which will be used to receive bug fixes until at least the next major release .
  • The qemu-0.10.0 changelog liss better KVM acceleration support, Bluetooth emulation and host passthrough support , Nokia N-series tablet emulation multiple vnc clients, and much more platform and hardware support. Eventually this might lead to qemu making current kvm-userspace obsolete, but that’s not for tomorrow yet.
  • Reuven announced Enomaly ECP 2.2.3, a maintenance release fixing some bugs .
  • And Matt announced openQRM 4.4 with SOAP Webservices for it’s Cloud , openQRM 4.4 now also implements “persistent appliances” which means that users can now “pause”, “unpause” and “restart” their Cloud appliances via the User-Portal. The internal billing mechanism will only charge active Cloud appliances and now fully provides the “pay-on-demand” Cloud Computing model. Also better integration for Puppet and Sshterm were added. More about it’s new features can be read on the openQRM site ..
  • And last but not least is the new ConVirt project that has just announced it’s 1.0 release .
    ConVirt is a centralized management solution that lets you provision, monitor and manage the complete lifecycle of your Xen deployment.

So that’s it’s for this week’s Open Source Virtualization updates 🙂
Be expecting more updates around the next VMWorld, or when the code is done 🙂
