In May , I mentioned that we introduced a checkbox in the Hyper-V UI for Windows 7 and Windows Server 2008 R2 which determines whether a virtual NIC is created in the parent partition for External Virtual Networks. (To get a better understanding of Hyper...

Our Virtual Switch got smarter in Windows Server 2008 R2. In Windows Server 2008, VMs are susceptible to MAC spoofing. MAC spoofing is where a (generally) malicious machine pretends to be another machine on a network (there are legitimate applications...

I had a couple of emails overnight asking whether it is possible to use Hyper-V Manager "v1" (as in KB952627 for Windows Vista SP1, or part of RSAT in Windows Server 2008) pointing to a machine running Windows Server 2008 R2 RC or Microsoft Hyper-V Server...

A cautionary note for those of you performing an in-place upgrade of a machine running Windows Server 2008 with the Hyper-V role enabled, to Windows Server 2008 R2 Release Candidate. During the installation, you will see the following compatibility...

I thought I’d start a series of posts highlighting some of the smaller changes in Hyper-V in Windows Server 2008 R2. There’ll be plenty of people covering the larger features such as Live Migration, so I figured someone needs to cover the other fun stuff...

The Hyper-V Security Guide is now available online or for download as a Word document. It covers hardening, delegation (including using SCVMM), and protection mechanisms for virtual machines. You can read it online here , or download the Word document...

Just a quick heads up – as posted on our team blog earlier this month, KB967902 resolves an issue in Hyper-V regarding a certificate expiration issue. This was released earlier today on Windows Update. A restart will be required to complete the installation...

OK, so I'm a couple of months behind the times.... but in case you aren't already aware, there's a free 400+ page Microsoft Press E-Book available online. It makes interesting reading and has an all-up view of Microsoft virtualization covering Hyper-V...

As Ben mentioned last year, creating a large fixed size VHD in Hyper-V can be a lengthy operation as we zero out the contents of the file during the creation process. In Hyper-V itself, there is no workaround to this. However Chris, a developer on...

"When I were a lad" (you have to say that in a northern British accent for authenticity), I used to catch the “ Number 64 ” bus outside Fairfield Halls in Central Croydon as a leg of my journey to Junior school. The busses never arrived as scheduled...

Just thought I'd add a quick blog entry - cool thing at the office today. Cans of Hyper-V ‘Pure Consolidated Energy for your Server’ turned up at our office this afternoon for the development team. Thank you marketing team! More info at www.serverunleashed...

Over the break I’ve been taking over Christmas, one of my goals was to move the remainder of my Virtual Server “production” VMs across to Hyper-V. But when nearing completion, I noticed that Server Manager was reporting a role error: Looking at...

While working on the next version of HVRemote yesterday evening, one of the things I wanted to address based on feedback from various people was to have the tool (written in VBScript) detect whether it is being run from an elevated command prompt. While...

Update 19th Nov - v0.3 now released! It has been a little quiet on the blog front, but sometimes, at least in this case, I hope I've come up with something worth waiting for. Announcing "HVRemote"...., a tool to "automagically" configure Hyper-V Remote...

When managing a large number of virtual machines, there is often a need to tag it in some way with one or more properties uniquely identifying it for administrative purposes. One example would be to identify a virtual machine as belonging to a person...

Today is (was) Virtualization Launch day. Although the keynote presentations were streamed live (in fact I'm just watching Bob Muglia finish up as I'm typing this), they will be available later this afternoon for on-demand viewing here . Some of the...

Curiosity got the better of me. When I was analyzing why Hyper-V Remote Management didn't always work over a VPN connection due to DNS the other day, I mentioned that I wasn't familiar with the replacement technology for CMAK in Windows Server 2003. Well...

For Hyper-V to operate correctly, it is strongly advised, and in many cases, required, to install the latest BIOS onto your hardware for hardware virtualization features to operate correctly. While some OEMs provide fantastic information, my experience...

This is a question I’ve seen come up a few times so figured it was time to examine why in a little more detail. In Virtual Server, you were able to copy VHDs and the associated VMC (Virtual Machine Configuration) file from one host to another, add...
