Hotfix: Guest may crash during live migration

We released a new hotfix for Hyper-V today.

This hotfix addresses an issue where virtual machines may crash (with a STOP 0×000000D1, DRIVER_IRQL_NOT_LESS_OR_EQUAL error) when it is being live migrated.  While this problem is relatively hard to encounter – I would encourage anyone who is using live migration to plan to deploy this hotfix in the near future, as you do

Converting to a fixed virtual hard disk–for a Server core installation

My last challenge for getting all of my server virtual machines over to fixed-size virtual hard disks is moving some of my Windows Server 2008 R2 virtual machines.  As a reminder, the goal here is to move a virtual machine on a large dynamically expanding virtual hard disk to a smaller fixed-size virtual hard disk. I have used the same

Time for some server maintenance

I have had a couple of days off for Christmas, and once the children were happily playing with their new presents, my mind naturally turned to some outstanding server maintenance that I needed to do.

Using “built in” applications with Windows XP mode

Last week I was asked, on Twitter, if it was possible to publish a built in application (like Internet Backgammon) from Windows XP mode.  The answer is: Yes, but it is a little tricky.

Most people use Windows XP mode to run specific applications that they have that will not run under Windows 7.  These people do not want to have

Why you should be using BitLocker on your servers

In Windows Vista we introduced “BitLocker” to Windows – a native full disk encryption technology for Windows.  Most people immediately saw the potential for BitLocker on laptops.  Encrypting your laptop meant that if you were ever unfortunate enough to lose your laptop (through theft or forgetfulness) you would not have to worry about someone else getting access to your data.

Creating virtual hard disks–the slow way

Over the weekend I reconfigured one of my main servers.  As part of this process – I had to make some large fixed virtual hard disks (800-1600GB in size).  This took a long time…

Testing data protection with virtual machines

Hopefully what I am about to say is not news to you – but it is worth saying: data protection systems that have not been tested are useless.  Whether you are backing up computers, using RAID or replicating data – the first thing you need to do once you have everything setup is to test that you are actually getting
