Moving VHDs for a virtual machine in Hyper-V on Windows 8.1

Thursday, 23 July 2015

I’ve been using virtual machines to test out some software, but those VHD files take up a bit of disk space – so much that my PC’s solitary SSD drive was running out of room. Thankfully the Lenovo hard disk drive bracket kit arrived today so I can install an extra drive to supplement the SSD.

Now to move the VHD files to the new drive.

The instructions described here, whilst for Windows Server are essentially the same for a Windows desktop OS. The only difference is that the Move Wizard doesn’t offer the Move the virtual machine option. eg.

Of course, you can do this with PowerShell too (and I did):

Move-VMStorage -VMName W12R2-1 -DestinationStoragePath d:\VHDs\W12R2-1

And you even get a nice progress bar!

You also get the migration progress in the status field in Hyper-V Manager.

A few minutes later, the VHD was successfully moved to my new hard disk, and because this happened live, the VM kept running the whole time. Impressive!

PowerShell and (not) parsing command lines

Wednesday, 22 July 2015

A short reminder note for myself.

To tell PowerShell to not parse the remainder of a line, use --%. This is invaluable when calling out to external commands and you don’t want to escape every special character with a backtick (`).

So instead of this:

icacls X:\VMS /grant Dom\HVAdmin:`(CI`)`(OI`)F

You can write this:

icacls X:\VMS --% /grant Dom\HVAdmin:(CI)(OI)F

See the Stop Parsing section in Online Help for more info.

Glimpse and Castle Windsor

Monday, 20 July 2015

Some breaking news in the last week – Microsoft has taken over the sponsorship of Glimpse – an open source diagnostic platform for web applications. Glimpse has been described as the server-side equivalent of your browser’s F12 Developer Tools, so it’s great that first Red Gate and now Microsoft have recognised the value of this tool and supported its development.

I’ve been making use of Glimpse recently to get some more insight into the timing of server-side code. It hooks into the ASP.NET pipeline and gives a useful breakdown of various activities. Depending on what you’re using with your web application, there’s extra extensions that you can add to glean more information – like Web Forms, Entity Framework etc.

Even for things like an Inversion of Control Container can provide interesting data. There’s already extensions for AutoFac and Ninject, but not for Castle Windsor – one of my preferred IoC containers.

I know that there are quite extensive diagnostics provided by Castle’s container – but usually you only see these when you’re debugging, so I thought it might be possible to expose the same information to Glimpse.

And so I created the Glimpse.Castle extension.

It adds a new tab to to the Glimpse dashboard with all that useful detail from the Castle container’s diagnostics service.

The extension source code is on Github and currently you can build it and run with the latest release of Glimpse. When I get a chance I’ll get it published on NuGet and get it added to the extensions page on the Glimpse website.

Visual Studio 2015 Launch

Saturday, 18 July 2015

Set your alarm clocks because the Visual Studio 2015 launch begins at 20th July 2015 15:30 UTC. (That’s 1am Tuesday morning if you live in Adelaide).

Or you can enjoy a good night’s sleep and watch the recordings on Channel 9 at a more sensible time Smile.

Either way, I’m definitely looking forward to the final RTM of VS 2015 – I’ve been using the Release Candidate version on and off over the last month or two and there’s definitely some nice enhancements.

Speaking at DDD Melbourne 6

Saturday, 20 June 2015

I’m excited to confirm that I’ve had a talk accepted for DDD Melbourne, a one day developer conference to be held on Saturday 8th August, in yes, Melbourne Smile(flights are booked!)

My “10+ unusual tips & tricks for .NET” presentation (previously featured online and at last week’s ADNUG meeting) is listed as one of the last sessions of the day before the closing locknote. ADNUG attendees will be able to confirm that I do indeed have more than 10 tips.

The agenda is now live - http://dddmelbourne.com/agenda

If you’d like to attend, you’ll want to set an alarm for 29th June at 12:30+0900 – as that’s when tickets go on sale. Last year they sold out in just 12 hours, so I wouldn’t be surprised if they go even quicker this time.

It should be a great event, and I’m really looking forward to being a (small) part of it.
