The last couple of days have been very strange and stressful for me.  The reason for this is that my home town – Brisbane, Queensland, Australia – is currently being flooded.  Thankfully all of my family is safe at this point in time – but it has been a very tense process as we have been following the news remotely and periodically trying to get in contact with different family members to find out what is happening. While everyone is safe – my fathers business is not.  My father (Wayne Armstrong – though we all call... [Lire la suite]

Using Hyper-V for a high-end desktop computer

I often get asked what my recommendation is for a high-end desktop computer for the virtualization enthusiast. The root problem that causes this question is the well noted issues with Hyper-V and high-end video cards.  Thankfully – this can now be a problem of the past. With Windows Server 2008 R2 we added support for processors that have second level address translation (Intel EPT or AMD RVI).  On these systems everything “just works”. Something that I can now attest to.  As an avid virtualization junkie and... [Lire la suite]

Slow mouse performance on Windows 2008 R2 virtual machine

eWeek Magazine published an article about how VMware plans to deploy security inside the Hypervisor in 2011. Allwyn Sequeira, who is Chief Technical Officer for VMware ‘s Security and Network Solutions divisions told a group of technical writers and analysts that security for applications deployed in cloud systems needs to be built into the hypervisor itself and not reside independently in the stack. "…When security is automated within the hypervisor — thus untouched by humans — data is going to be far better protected. This... [Lire la suite]

Virtualiser une application Web nécessitant JAVA alors qu'une version de JAVA est déjà installé en local sur le Pc

Dernièrement, il a fallut que j'utilise App-V pour utiliser plusieurs version de Java sur le même poste. Ce qu'il faut savoir, c'est que lorsque l'on test l'application web virtualisée sur un poste client où une autre version de Java est installée en local, on s’aperçoit que la JRe installée en local et la JRE virtualisée ne s'aime pas beaucoup et entre toutes les deux en conflit, et plus particulièrement, le navigateur internet ne lance pas de JRE car il ne sait tout simplement pas laquelle il faut exécuter (oui, IE n'ose pas prendre...

Bilan virtualisation 2010 : Après les serveurs les postes de travail

Après le stockage et les serveurs en 2010, la virtualisation est appelée à se renforcer sur les postes de travail en 2011.

Microsoft releases Server App-V first build

Just before the end of the year, as promised, Microsoft released the first early beta of Server App-V, one of its most ambitious virtualization platforms. App-V technology derives from SoftGrid, the application virtualization platform that Microsoft inherited with the acquisition of Softricity in May 2006.Considered a leading solution before the acquisition, it didn’t become a mainstream platform despite Microsoft resources. This depended on several factors: the decision to relegate App-V in the controversial Microsoft Desktop... [Lire la suite]
