Compacting Virtual Hard Disks in Windows 8 / Windows Server 2012

Recently the “Ask the Core Team” blog did a great post about compacting a dynamically expanding virtual hard disk in Windows 8 / Windows Server 2012. You should check out their full post for the details, but the summary is that you now need to manually mount the virtual hard disks in the management operating system prior to trying to compact it. This is something that we used to do automatically for you – but we had reports of problems when we were attaching and removing virtual hard disks when the system administrator was not...

The different ways to compact a disk

Today if you want to compact a virtual hard disk – you can use Virtual PC / Virtual Server / Hyper-V or Windows 7.  But not all methods are the same.  Under the covers there are two different approaches that are taken to compacting virtual hard disks: Virtual PC / Virtual Server: Perform a blind “block level” compaction.  Here the virtual hard disk is inspected at a block level, and when a block is found which is full of zeroes, the block is removed from the virtual hard disk. More accurately, zeroed blocks are... [Lire la suite]

Mike releases WIM2VHD

Mike Kolitz has just released "WIM2VHD".  This is a tool that allows you to take the WIM file off of a Windows 7 or Windows Server 2008 R2 install DVD and turn it directly into a virtual hard disk that can be used by Hyper-V, Virtual Server or Virtual PC.  Not only is this handy - it is *fast*.  Usually under 10 minutes to get up and running. You can download the tool from here: http://code.msdn.microsoft.com/wim2vhd And you can read more about it (and see a video guide) on Mikes blog here:... [Lire la suite]

Expanding Virtual Hard Disks with Hyper-V

One of the most frequent questions I see on forums and newsgroups that deal with virtualization is the age-old question of "I have used all the space inside a VHD hard disk. How do I expand the virtual hard disk to make room for additional data?". Luckily for us, with Microsoft Hyper-V on Windows Server 2008, this is now possible. Hyper-V now adds the ability to increase the maximum size of a virtual hard disk.  Expanding the disk increases the storage capacity of a dynamically expanding virtual hard disk or a fixed...
