On Monday March 23rd, VMware released a Cost-per-Application Calculator. This calculator enables you to calculate the cost per VM (or application, as VMware suddenly calls them). This tool steers away from comparing solely purchasing costs of the software licenses of the virtualization solution, but introduces a ‘Cost per Application’ metric.

I’ve been installing a Microsoft Windows Server 2008 R2 VM for filesharing in my VMware Lab Manager Environment. Because it is a Virtual Machine, I need to install the VMware Tools.
However, I ran into a problem while trying to launch the installer (setup.exe) from the command prompt
the subsystem needed to support the image type is not present
After some googling I found only a single hit on this problem: “More PowerShell Remoting“. David Clarke posted the solution:

Yet another reason not to use Hyper-V
While fiddling around with the new Microsoft Hyper-V R2 beta, testing out CSV, Live-Migration and the lot, I suddenly realized that Hyper-V does not support restart priority in cluster (HA) situations. This could very well be my next big reason not to recommend Hyper-V to customers, as HA (clustering) is useless without restart priorities.

Most of you will have noticed the regular downtime or incredible slowness of the Virtual Lifestyle website. I’m running this website on a VMware ESXi 3.5 build 130755 machine. A couple of days ago, I ran the command ‘vmkgdbd’ by accident, and might be the cause of all the problem’s I’m having.

I’ve been reading up on loads of articles dealing with the differences and similarities between hypervisors. Lots of these articles compare different hypervisor performance-wise.
Here are some of the blogposts comparing hypervisors and/or management tools:
- Prestaties van Hyper-V, XenServer en ESX vergeleken
- VMware ESX slaat Hyper-V knockout
- Presentation: Hyper-V vs ESX in the datacenter
- Lab Experiment: Hypervisors
- Say it isn’t so: Hyper-V and XenServer outperform ESX
- Reaction to “Say it isn’t so: Hyper-V and XenServer outperform ESX”
- Lack of VMware Resource Pool awareness
- Destruction of VMware vCenter templates
- Botched management of VMware ESX port groups
- Unnecessary ISO image file proliferation
- PRO Tips not working as expected for ESX hosts
- Disconnect of VI Clients on SCVMM restart
- Manual cleanup required after SCVMM-VI3 integration

A couple of days ago, I recieved an invitation to join the SUSE Studio alpha. At VMworld, I attended the break-out session “The Future of Linux is Software Appliances” by Nat Friedman, Chief Technology and Strategy Officer Linux at Novell. He talked about the inefficiences of a OS, seen from the ISV’s point of view.
Today the Linux world is dominated by one-size-fits-all Linux distributions that include thousands of packages and that can be two or three gigabytes fully installed. In this presentation, Nat will introduce the benefits of streamlined, single-purpose software appliances based on Linux — in the form of virtual machine images, bootable and installable media, or live USB keys.
Nat will also show some exciting new technology that’s being developed inside SUSE that will make it fun and easy for you to treat Linux distributions like lego sets to create your own custom Linux appliances.
