Virtualization Review's hypervisor test: The other day, Virtualization Review published a comparative performance test of three hypervisors: VMware ESX 3.5, Windows Server 2008 Hyper-V and Citrix XenServer. You can see it here. NOTE - there are few independent, published performance reviews of hypervisors because including ESX in the review without VMware's permission violates the VMware EULA about posting benchmarks. Amongst reviewers, this EULA restriction is well-known as serves as a deterrent. Rick Vanover and his editor, Keith Ward, deserve kudos for securing VMware approval for the performance comparison without jeopardizing journalistic integrity. Way to go! OK, back to Rick Vanover's test. His test objectives: All the hypervisors offer essentially the same base functionality. In this series of tests, the objective was to put the same workloads on each one and see how they stack up. The types of workloads tested varied, to simulate a typical environment in which some virtual machines (VMs) are stressed, and some aren't. Each platform was subjected to the same test plan parameters, to give a fair accounting of their performance. Read about the comparison parameters, test environment and caveats. The results will be surprising (in a "man bites dog" sort of way) to many. Read More...

Microsoft at VMworld Europe 2009: VMworld Europe's tagline this year is "virtually anything is possible". Kinda reminds me of Mike's blog post on Monday about Red Hat. And for many IT pros, "virtually anything is possible" might apply to the fact that Microsoft is exhibiting at, and sponsoring, VMworld Europe for the second year in a row. Tres bien, as they say in Cannes. So if you're one of the 3,000 paid attendees expected at VMworld Europe 2009, below's a sneak peak at what you'll find inside booth #133. If you're not attending, I'm going to attempt to post some pix ... maybe video if I'm lucky ... from the booth so you can see the action. No doubt there will be plenty of other blogs coming from VMworld Europe. You can see most of them at the Virt blog aggregator. So what am I expecting to see in Cannes? Outside of the Microsoft booth, I'd expect to see early versions of client hypervisors, interop announcements, new product packaging, cloud computing announcements, and likely an update about VMsafe. Should be a busy week. Read More...

The Virtualization Essentials from Citrix: Bonjour from Cannes. This is just a quick post about Citrix making public the Essentials for Hyper-V news. It's been talked about already by Alessandro and others. Read More...

Guest post: virtualization requires the proper perspective: In the past few weeks following the Microsoft virtualization launch event in Bellevue the virtualization buzz keeps growing louder and louder. We keep hearing more and more from customers that virtualization is a key component of their IT infrastructure strategy. IT organizations fall across a wide spectrum of virtualization implementation and sophistication. Some have been doing it for quite some time, while others are just starting or even just starting to think about it. One thing that keeps coming up over and over, however, is the notion of using virtualization as an enabling technology, rather than an end in itself. This means aligning your IT strategies to your business strategies. Ultimately it’s not about how many virtual guests you can run on a physical host, or how cool your underlying infrastructure is – it’s about using these technologies to achieve better business outcomes. Whether the specific goal is to use virtualization to save money, reduce data center footprint, gain competitive edge, drive business continuity and availability, or go green by reducing power and cooling, it all comes down to using virtualization as a means to reach these goals. OK, so that makes sense – so how do I do that? One of the key things that HP and Microsoft recognize is that it is the management tools that really enable you to take advantage of the underlying virtualization technologies. Microsoft System Center, especially with System Center Virtual Machine Manager 2008, will provide easy to use tools that will allow you to manage your physical and virtual environments from a single pane of glass. This means customers won’t have to use one set of tools to manage their physical infrastructure and another set to manage their virtual environment. Read More...

The Validated Hypervisor: By now you might have seen that VMware ESX 3.5 update 2 has passed the Microsoft Server Virtualization Validation Program. They announced it here. today announced it has qualified its industry-leading VMware ESX hypervisor under the Microsoft Server Virtualization Validation Program (SVVP). VMware ESX 3.5 update 2 (ESX 3.5u2) is the first hypervisor to be listed under the program, providing VMware customers who run Windows Server and Microsoft applications with access to cooperative support from Microsoft and VMware. Of course we all read that VMware only agreed to participate in SVVP a couple weeks ago, around the time we announced expanded technical support for 31 server applications running on validated hypervisors. Congrats to them for achieving a validated configuration so quickly. ESX 3.5 update 2 now joins Windows Server 2008 Hyper-V as being validated to run Windows Server and associated Microsoft server applications. And now that ESX 3.5 has passed SVVP, VMware customers will join Novell customers as receiving cooperative technical support (if there's a support policy in place, and the customer is running the validated configuration) for Microsoft software running in/on their virtualization software. I'd expect to see other hypervisors pass the SVVP soon. There are 7 vendors now committed to participate in SVVP, the newest addition being Unisys. Patrick Read More...
