Hyper-V now allows you to configure a startup, minimum and maximum memory limit.  If you are like me – you probably leave the startup ram at the default of 512mb – but you should really consider changing it to better suit your environment.  Here is a quick screenshot from one of my Hyper-V servers: Two things that I have discovered: Some of my virtual machines benefit from having a startup and minimum that is below 512mb.  My FTP server, for instance, is a core installation of Windows server which just acts as an...

Last week I posted about how you can now use Windows Server Backup in Windows Server 2012 to backup virtual machines.  One of the first questions that people had was “how do I do this from the command-line?”  So – let me show you! The tool you will want to use is “wbadmin.exe” Backing up a virtual machine is fairly straight forward.  Your command will look like this: wbadmin start backup –backupTarget:<location to backup to> –hyperv:<list of virtual machines to backup> --> Please see the rest on the...

La déduplication est une des nouvelles fonctionnalités de Windows Server 2012. D’habitude quand la chose est trop belle, j’ai tendance à considérer que c’est trop beau, qu’il y a forcément un piège.   Une très bonne idée de la déduplication dans Windows Server 2012, c’est qu’il est possible de l’essayer sans l’activer. Plus précisément, on a juste à installer le rôle et utiliser l’utilitaire DDPEVAL.EXE. Il se chargera d’évaluer l’espace disque qu’on est en mesure d’économiser. Dans l’illustration ci-dessous, c’est le volume... [Lire la suite]

One thing you may not know is that when you add a disk to a Windows 2012 virtual machine under vSphere 5, it gets added and tagged as removable. The consequence of this tag is that when you try to access that disk using \\servername\e$, a popup message appear: "Windows cannot access \\servername\e$ You do not have permission to access \\servername\e$. Contact your network administrator to request access." If you look on the security log of your Windows server: an audit failure should have appeared --> please see the rest on... [Lire la suite]
