Will Workstation 6.5 bing us Unity ?
I found an intresting story on the ChipX86 blog about Unity support in the upcoming new version of Workstation, but will this version also support ESX 3.5 with a running VM? Earlier this year, VMware released VMware Fusion 1.0 for the Macintosh. This was their first virtualization product for the Mac and it has been met with high praise. And jealousy. VMware Fusion managed to change how users thought about virtualization. Thanks to Unity, you were no longer forced into having a big box on your screen. With the click of a button, the applications inside your virtual machine would appear outside of the box, sitting alongside your other applications. The Mac users loved this and Windows and Linux users were left feeling like they missed out. Workstation 6.5 will include support for Unity, allowing your Windows and Linux programs to intermingle with the click of a button. VMware just released initial support in their Friends and Family beta for this. Their public beta 1 will include this feature in a vastly improved form.

Running ESX 3.5 in Workstation 6
I have installed ESX 3.5 using the Xtravirt white paper. So far so good, ESX 3.5 starts, but when I want to start-up a Virtual machine there’s trouble in paradise. I receive an error and my ESX 3.5 server crashes with a core dump. There’s running one Dutch thread at the vmug.nl site and I posted a comment to the VMware community. But nobody is responding. Any ideas ?

Performance Characteristics of VMFS and RDM
VMware published a whitepaper about Performance Characteristics of VMFS and RDM. VMware ESX Server offers three choices for managing disk access in a virtual machine—VMware Virtual Machine File System (VMFS), virtual raw device mapping (RDM), and physical raw device mapping. It is very important to understand the I/O characteristics of these disk access management systems in order to choose the right access type for a particular application. Choosing the right disk access management method can be a key factor in achieving high system performance for enterprise?class applications. This study provides performance characterization of the various disk access management methods supported by VMware ESX Server. The goal is to provide data on performance and system resource utilization at various load levels for different types of work loads. This information offers you an idea of relative throughput, I/O rate, and CPU efficiency for each of the options so you can select the appropriate disk access method for your application.

Mike Laverick did it again
Mike Laverick has created a new RTFM Guide. His latest edition covers all of the new features and enchantments we can find in the ESX 3.5 release. His Guide concludes with : As you can see VMware have once again added new functionality to both ESX and VirtualCenter at no additional “upgrade? cost. Additionally, there has been some significant finessing of existing features which make the administration of VI-3.5 easier. The core product remains the same despite the introduction of DPM, VUM and Guided Consolidation. So anyone reading the VI-3book will still find lots of useful and relevant material between its covers. The authors of the VI-3book will continue to maintain and updates its content as the VMware Infrastructure 3 evolves. These updates will supplied as free PDF files which can be downloaded from VI-3book.com. However, it seems like the next big release for VMware will be VMware Infrastructure 4. The photo taken by Viktor van den Berg at the VMworld2007 in SF where I conducted an interview about the upcoming VI3 book.

The VMware Infrastructure SDK Packages are updated
There are some new features in the SDK release that goes along with ESX 3.5. The VMware Infrastructure Web Service API on VirtualCenter 2.x or ESX Server 3.x. Latest Version: 2.5.0 | 12/10/2007 | Build: 64154 gives access to Managed Objects like the FileManager, VirtualDiskManager and ViewManager. Alltough these objects are still experimental and subject to change in future releases they give us great possibilities. You can get the VMware Infrastructure SDK 2.5.0 Sample code, documentation and the WSDL for developers using at the following link:http://www.vmware.com/download/download.do?downloadGroup=VC-SDK
