At a customer site we received several notifications of performance issues with a VMware VI3 environment. After having checked the configuration of the VMs and the Hosts we decided to dive into esxtop. At first sight we did not see any abnormalities. Low %RDY, which is usually the first thing I check, some swapping but not enough to cause any major delays. The weird thing about this one is that it seemed that only when IP was sent/received the VM felt sluggish. As we could not reproduce the issue we decided to start esxtop in... [Lire la suite]

The Dynamic Data Center Toolkit for Hosters project have just put up the sample code for a Hyper-V ActiveX RDP control, available here: http://code.msdn.microsoft.com/ddc/Release/ProjectReleases.aspx?ReleaseId=3833 What this allows you to do is to create a Remote Desktop connection directly to the virtual machine (not to the guest operating system) in exactly the same manner as when you are using the Virtual Machine Connection window in the Hyper-V Management Console.

Que ce soit au niveau des serveurs, des applications ou du poste de travail, Microsoft ne ménage pas ses efforts pour rejoindre ses concurrents partis beaucoup plus tôt. Pour autant, des lacunes demeurent. En matière de virtualisation, Microsoft part de loin. Fin 2007, l'éditeur ne proposait en effet que Virtual Server 2005, un hyperviseur qui ne répondait pas aux contraintes de la production. De fait, ce produit n'était guère utilisé que par des développeurs, tandis que VMware monopolisait le marché. Mais depuis 2008, l'éditeur... [Lire la suite]
