VM /ETC

Citrix has opened the Citrix Synergy 2009 Conference in Las Vegas, NV this week with a flurry of press releases announcing new products that provide innovative methods for delivering corporate published applications. Adopting a model similar to satellite TV providers, Citrix Receiver, Dazzle, and Merchandising Server provide end users the ability to choose their own applications, and then those applications are available not only on the desktop but from any device, anywhere.

This model offers the potential to lift a huge burden from the IT department when provisioning both physical and virtual desktop infrastructure (VDI). At the same time, on demand self service applications also introduce software as a service provided by a company store delivery concept. For example, the IT department can build a standard desktop image or template virtual machine (VM) that consists of just the operating system and basic enterprise applications like anti virus and asset monitoring software. Then, based on familiar and easy to use TV programing -like subscription options, the end user has the control to choose which applications are delivered to their desktop via the combination of Citrix Reciever and Dazzle. These same applications or virtual desktops are also made available from the home PC or the iPhone without compromising administrative centralized security and control. New application choices and version updates are continuously provided via the “company store.”

Apparently, all of these new Citrix products are free. Reciever and Merchandising Server are available today. According to the Citrix press releases “both Receiver and Merchandising Server require infrastructure products from the Citrix Delivery Center product family to complete their operations.”

The following is a summary of links to the official Citrix announcements with some key quotes from each.

I’ve heard VMware briefly speak about the Virtual Machine Interface (VMI) standard for the last few years. For example, it seems VMI is always a topic during one or more of the Keynote sessions at VMworld. However. I can’t recall ever hearing about VMI in the real world – that is , hearing about the progress of different operating systems integrating VMI. So, when I read the Techworld article Novell gives Suse kernel a VMware boost it made me realize that the open virtualization standard is alive and well. In fact, after a little research I discovered that popular GNU/Linux distributions now ship with VMI support enabled by default.

First of all, what is VMI? VMware has a couple of web pages on the subject. The Transparent Paravirtualization page provides a good introduction. Read the rest of this entry »

Bush – Everything Zen

Xen, XenSource, XenServer, and Zen. What are they? Which one do I use to virtualize my servers? What is Citrix’s product and how does it compare to VMware? These are my reasons for writing this post. Frankly, I was confused. After some intense meditation I decided to figure it out. Unfortunately, Lakers coach Phil Jackson was not available to help.

Wikipedia was where I started my journey. At first I was even more confused when I landed on the Xen (disambiguation) page: Read the rest of this entry »

Shortly after Oracle announced their new free Xen-based virtualization product VMware sent an email to all it’s partners addressing the confusion caused by Oracle’s claims. The following is a cut and paste from the email I received:

What Was Announced?

Oracle announced Oracle VM at their Oracle OpenWorld user conference. Oracle VM is a Xen hypervisor based on Oracle Enterprise Linux. Oracle also announced that the Oracle Database, Oracle Application Server middleware and selected applications would be certified when run in Oracle Enterprise Linux virtual machines on Oracle VM. Oracle claimed that Oracle VM is more efficient than other virtualization products. Oracle VM is free, but annual support costs are $499 for two-socket systems and $999 for unlimited sockets.

Oracle Press Release:
