SCVMM Self-Service Portal

The Self-Service Portal is a web application provided as part of the System Center Virtual Machine Manager, and allows “non admin” users to be able to work with specific VMs, and possibly even have the right to deploy new ones. Being a web application, the interface is accessed via a browser – the opening page…


Hyper-V VMs in a Lab Environment

Before I start, a note on “differencing disks”… these are .AVHD files which contain a list of the changed sectors when compared with a parent VHD, and their data, and they are always dynamic. Without its parent, a differencing disk is useless – they can be considered similar to a “differential backup” (relying on the…


SCVMM Console-ation – Addendum

Update to my blog entry from March 30th, there is now a public KB article describing the issue. Exactly the same information (I did the tech review), but it’s a more “official” article.


SCVMM Console-ation

The Microsoft System Center Virtual Machine Manager, other than being a mouthful to say and hence referred to as SCVMM, is a great consolidation tool for managing Virtual Server, Hyper-V and even VMWare ESX hosts and the VMs on them. This isn’t a sales blog, so if you’re not already familiar with the product then…


Avoid expansion if you’re snap-happy

Occasionally the purpose of snapshotting VMs in Hyper-V is misunderstood (and hence misused), and people find that their initial guesstimate as to required disk space was insufficient, so try to extend it after the fact. If there was an eleventh commandment, it should possibly be “Thou shalt not expand a VHD file if it hath…


Hyper-V VM State Dump Tool

Hyper-V Data Exchange Service & “Error 87: The parameter is incorrect” on startup

Recently we came across a case where Windows Server 2008 and Windows Server 2008 R2 servers running under Hyper-V were all failing to start one of the (five) Integration Services offered by the host. The services created by the Integration Services are: Hyper-V Data Exchange Service Hyper-V Guest Shutdown Service Hyper-V Heartbeat Service Hyper-V Time…


Hyper-V Virtual Networks

The most common questions that I get on Hyper-V setups relates to the networking configuration, and it seems to be common thing to get wrong, so I’ll try to go through the 3 types of virtual network we have, and how they differ.   A private network can only be used by the child partitions,…


Managing a standalone R2 Hyper-V from domain-joined Windows 7 client

After doing an in-place upgrade of my Windows Server 2008 SP2 Hyper-V host to bring it up to Windows Server 2008 R2, I decided to have a bash at setting up the Hyper-V management tools on my Windows 7 client. My setup is as follows: w2k8 – Windows Server 2008 R2 x64 – Standalone server…


VM Networking Improvements in Hyper-V in Windows Server 2008 R2

On the What’s New in Windows Server 2008 R2? page you can see one of the improvements for Hyper-V has been improved virtual networking performance, and specifically “offloading” has been extended through to the child partitions for those physical NICs that offer it. I did an in-place upgrade of my home server today, from Windows…
