Hyper-V Replica DC not working

I used the capabilities of Hyper-V 2012 to create a test environment that mirrors production systems (including a Domain Controller).  I couldn’t get the other computers in the environment to use the replica for authentication.  After a little more testing, I figured out that I couldn’t open AD DS on the DC.  Lots of searching […]

Failed to power on with error the process cannot access the file

I have been moving some of my Hyper-V installs from 2008 R2 to 2012.  Because of the large number of VHD’s attached to a particular VM, I elected to disconnect the disk from the old host and connect them to the new host, and then do an import. I did this on a few smaller […]

Error (415) adding a host to SCVMM 2012 sp1

I kept having errors adding hosts to a VMM server, even though all of the prereqs were met.   I received the following errors every time I tried to add the hosts: Error (415) Agent installation failed copying C:\Program Files\Microsoft System Center 2012\Virtual Machine Manager\agents\I386\3.1.6011.0\msiInstaller.exe to \\<hostname>\ADMIN$\msiInstaller.exe. The specified network name is no longer available Recommended […]

Hyper-V host blank black screen

I recently had a problem with a couple of IBM Blades that I was trying to deploy as Hyper-V hosts.  I employ the use of a replay volume from our Compellent storage to create an image for my blades.  Basically, I install one, sysprep it, and then copy the volume mount the copy as the […]

SCVMM and P2V Adventures

Where I work, we have been using Microsoft Virtualization since Virtual Server was in Beta.  Of course, we don’t necessarily use all of the functions and features of all the software we have, but one feature that I have used a good bit is the “Convert physical server” action in System Center Virtual Machine Manager.  […]

“netvsc” error in Hyper-V guest

We use Citrix Presentation Server for a number of applications, and lately we have had a significant increase in issues with one set of our Citrix servers.  We have 3 main sets of Citrix servers and the problems have only been happening on one set.  One of the sets doesn’t have this error, but wouldn’t […]

Error installing Integration Services on Hyper-V VM

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 […]

Hyper-V and DPM – Some issues that you may see

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 […]

Time Travel?

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 if he removes one of […]

P2V fails at Copy Hard Disk

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 […]
