  • Blog Post: Hyper-v and Snapshots (Part 1)

    We often talk about "rolling back" to a snapshot, but here, some of the snapshots we can apply aren't simply forward or backward, hence Hyper-V talks about applying snapshots. It also talks about Deleting snapshots which causes some confusion. Deleting a snapshot means foregoing the ability...

    We now have a UK AD user group ( ADUG ) And they have their first meeting set for October 23rd at Microsoft’s offices in London, from 6 till 9 in the evening. They’ve managed to secure John and Sally – probably the best established AD double-act in Europe (their tech-ed sessions are always among the...
  • Blog Post: A little more on PowerShell

    I've been showing PowerShell on the roadshow, and Steve warning me about it becoming the "Look-how-clever-I-am-with-PowerShell show". Actually, I quite like the idea of a "Look-how-clever-PowerShell-makes-you show". Working on some of bits and pieces of PowerShell for managing hyper...
  • Blog Post: Virtualization road show

    Earlier in the week we took the virtualization tour over the Irish Sea. Tuesday was Belfast – and with the snow, getting there was quite a challenge. I felt ill all day and didn’t think I’d delivered the content as well as I should have, but the feedback forms were really positive, better than I thought...
  • Blog Post: Looks like September for SCVMM

    The most senior Microsoft person ever to tell me off for something did so for my repeating of something which was circulating at IT-Forum last year - that there was a plan to sync up the release of the new version of System Center Virtual Machine Manager and Hyper-V. Obviously the two product teams want...
  • Blog Post: Hyper-V PowerShell library - now on Codeplex

    I've decided to go ahead and post the PowerShell library I have been working on to Codeplex . I wanted to explain various bits of it here before pulling it all together, but that is taking more time than I wanted. I've provided early copies to a few people - John Kelbley  used them to good effect...
  • Blog Post: How to: have nicer Active Directory management from PowerShell – without upgrading AD

    One of the first books I read on PowerShell  had a comment about using AD from the PowerShell V1 which amounted to “It’s too hard, don’t bother use VB Script instead”. I’d taken against the book in question (no names no pack drill) – in fact it reminded me of something Dorothy Parker is supposed...
  • Blog Post: Fun and games with VHD files in the new OSes

    One of the new features for both Windows Server 2008 R2 and the Windows 7 client is support for Virtual Hard Disk files built into the OS. You can create fixed or dynamic disks and “attach” the tools for Hyper-V call this “mounting” a VHD and early stuff on 7 seems to  have called it surfacing a...
  • Blog Post: PowerShell and the smarter command line.

    I mentioned I was doing some PowerShell work to manage configuration on the R2 versions of Windows Server 2008 Core and Hyper-V server (which now support PowerShell), and somebody in Redmond asked me if I knew  there were tools out there to do this job. … I was thinking about how we find stuff,...
  • Blog Post: Screencast and Q&A: Hyper-V integration components Disk and Network behaviour

    I had a really nice mail over new year from an influential IT Pros with more than a passing interest in Virtualization. It would be unfair to identify him, but I was very pleased to read "Yours is always one of the blogs I point our staff toward to get up to date information and idea of how the various...
  • Blog Post: It is done.

    Windows Server 2008 and Windows Vista Service Pack 1 have released to manufacturing . Actually it caught me by surprise because I was expecting it to happen later this week.

  • Blog Post: Doubts and Powershell, Hyper-V KeyValue pairs and Hash tables.

    I've said a number of times that I think technical people are rarely secure in their own abilities; that they have a demon on their shoulder who whispers "You're not really, that good" ... "They'll find you out one day". I was talking to a colleague this week who seems to be racked...
  • Blog Post: Product life cycles (and Virtual Server 2005)

    It's always nice when someone says James O'Neill, IT Pro Evangelist at Microsoft, reveals that Virtual Server 2005 support will end in 2014 - except that then people come and demand to know why you're revealing product plans. So, lets start with a basic question . "Where do I go to find out when support...
  • Blog Post: Hyper-v Server , what is it exactly ?

    I’ve got multiple blog posts on the go in Windows Live Writer at the moment, one talking of the relative dearth of posts recently. Last week the folks at VMware put up another post about Hyper-V server and in it actually found something nice to say about me (even if they mis-spelled my name. double-L...
  • Blog Post: Setting up Domain controllers on Server Core.

    One of the things I have pointed people to a few times recently  is the Windows Server Core document in the step by step guides for Server 2008. Want to know how to install a role ? It's in there. Configure TCP/IP from the command line ? That's there too. Put in the key that you skipped during installation...

  • Blog Post: The Hyper-V API - Disks

    In an earlier post in this series (several posts ago now) I showed how the Msvm_virtualSystemManagementService WMI object can be used to configure resources in Hyper-V, and I started with the easy step of setting memory and CPUs which exist on a freshly created virtual machine. What about Network Cards...
  • Blog Post: It's rude to laugh at other people's misfortunes - even VMware's

    That was one of my mother's regular sayings when I was young. OK Not the bit about VMware. So I didn't laugh when I saw a thread on VMware's community forum entitled BIG bug in ESX 3.5 Update 2 - If you're using 3.5u2 read this now! - A general system error occurred: Internal Error .

  • Blog Post: Support for Red Hat OSes on Microsoft Virtualization (and Vice Versa)

    One of the questions which comes up on our internal distribution lists for Hyper-V is “when will such and such and OS be supported on Hyper-V” and the somewhat frustrating response is usually in the form “We’re talking to OS vendors, but we can’t talk about contract negotiations while they are going...
