I was trying to change from a “Legacy Network Adapter” to a “Network Adapter” on one of my Hyper-V VMs. I added the “Network Adapter” and removed the “Legacy Network Adapter”, and started the machine up. When the machine came up, it wouldn’t connect to the network. Having seen this before I knew exactly how [...]
We have several (15 or so) Hyper-V hosts running a number (126 or so) guests. We use DPM to backup our servers, but only a few of our VMs are backed up at the host level. Most are backed up as regular clients. I have been having trouble with a couple of the ones that [...]
Evidently, Windows Server 2003, running on Hyper-V, is confused and thinks it must be time traveling. Read below for the details…
(Event ID 1054) Windows cannot obtain the domain controller name for your computer network. (An unexpected network error occurred.). Group Policy processing aborted.
The customer explained to us that [...]
I have been trying to get a P2V of a production system to use in our DR plan. I have limited opportunity to do this, because I am not allowed to impact performance during production hours for this system, and the definition of production hours is fairly broad. I have been trying for a couple [...]

Of the new features coming in the R2 versions of Windows Server 2008 and SCVMM, I think these two are the obvious winners:
Support for Live Migration: With Windows 2008 R2 adding support for Live migration, it’s now added as a new migration option in VMM R2. Live migration requires the source and destination host to [...]
I managed to convince the “powers that be” that we didn’t need to have a dual quad-core server with the capacity for 32GB of RAM to and connectivity to our SAN sitting around doing nothing until they occasionally use it for upgrade testing… So I did a P2V (Physical to Virtual conversion) and shut down [...]
If you want to monitor performance in Hyper-V, you might like to check out this utility:
If you use Hyper-V, or any OS virtualization platform, you know that you can’t trust the Windows Task Manager from inside the VMs to tell you squat. Basically, the virtualization layer pulls the rug out from under the guest [...]
I have several Hyper-V host systems and I am very happy with the performance and manageability. I did recently have an issue with one of them though and it took me a while to figure out how to correct it.
I was attempting to fix an error in the Virtual Machine Manager console and I restarted [...]
I was going to extend a volume on one of my Server 2008 Core machines, and it told me “there is not enough space to perform this action”…
There was however enough space, but for some reason Microsoft Forefront decided that I shouldn’t be allowed to extend a volume remotely. So I disabled the services and [...]
