Hyper-V Server 2008 R2 Host backup (wbadmin)

Hyper-V Server 2008 R2 Host backup (wbadmin)

After using Hyper-V Server 2008 R2 (Free edition), I have a question about how to backup the Host.

I did research on Internet, most people is talking about using Windows Server Backup to do Host backup. Their instruction is based on Windows Server 2008 GUI.

Then, I tried to use the general server core approach to add Windows Server Backup to Hyper-V Server 2008 R2 to see if it works or not.

And the testing result is positive.

Steps for adding Windows Server Backup in Hyper-V Server 2008 R2

Step 1: Check if Windows Server Backup is installed by using the following command


Step 2: Use the following command to add feature
ocsetup WindowsServerBackup

Step 3: Check again to see if Windows Server Backup is installed

Step 4: Use the following command to do system backup with system state
wbadmin start -backuptarget:p: -allcritical -systemstate

Step 5: Backup completed

Failed to start VM in my i7-2600K Hyper-V server 2008 R2

MS Hyper-V R2 SP1 (workgroup), Virtual Machine failed to change state


1. Download Hyper-V R2 SP1 from

2. This server is running in workgroup mode

3. Disable firewall for all profiles

4. Enable all remote access through sconfig

5. Connect through Vista and Win7 in same workgroup with using Administrator account (Same administrator’s password on all machines)

6. hosts file modifed with adding hyper-v server name and IP

7. Windows firewall is disabled on all clients and server.

8. HRremote run to configure anonymous DCOM on client.

9. Remote Management can access to Hyper-V server and create Virtual Machine.


When I start Virtual Machine. It has the error message “XXXXX failed to change state”.

I tried to simulate this issue with W2K8 R2 to the same machine. But this issue does not appear in W2K8 R2. I faced this problem in MS Hyper-V R2 SP1 only.

I re-installed 3 times and this issue can be reproduced in my machine.

I tried W2K8 R2 Standard (Full and Server Core) without problem. I can use my Vista to manage it succesfully.

I checked in event viewer. It has an event 3040.

Finally, I find out a hotfix which is related to this issue.

KB2517374: “You cannot start virtual machines on a computer that is running Windows Server 2008 R2 and on which a CPU is installed that supports the AVX feature”

After applying this Hotfix, I can start the Virtual Machine.

MS will not provide hardcopy certificate anymore

Today, I receied July 2009 MCP Flash. It has big news. MS will not provide hardcopy certificate by default. If you need hardcopy, please pay $$$.

In my career, I took a lot of MS exam and got a lot of MS certificates. If they need me to pay extra $$ for my certificate, I will consider to end my MS certificate plan.

If you are not agree to MS new certificate arrangement, please goto the following url to express your angry and complain.

I left my comment to this url too.

Actually, I paid a lot of effort to take different MS exam from NT4 to Windows 2008. If exam will not provide paper printout certificate any more, I consider to discontinue my MS cert path in coming future. And in my peer group, I am one of the driver to encourage my peers to take MS exam. In coming, I will discourage my peers to take MS exam and technology. I am strongly disappointed to this arrangement.

I would like to propose the following suggestion for MS if they are really consider to our voice.

1. establish a plan for existing holder to choose to maintain the existing plan. They can order paper certificate w/o paying extra shipping and handling charge

2. Discount the exam fee (Not a short period to CHEAT user), deduct whole shipping and handling fee.

3. Send me an official email and tell me that it is MS new arrangement.
And please note it in the email “if you don’t accept it please do not use MS product”.

I am vvvvvery angry w/ this new arrangement.

I just planned my OCS and W2K8 virtualization in coming months. I will cut it. And I won’t suggest OCS as Enterprise Voice and IM solution to my customer. I will not suggest Hyper-V as Virtualization platform.

I will not take Win7 exam for driving new Desktop deployment.

Virtual Server to VMware Server

Previously, I built my testing lab by using Virtual Server 2005 SP1.
Currently, I am running VMware Server 2.0 (64-bit) in my Vista box. And I am going to convert vhd file to VMware Server.

I downloaded VMware Converter 4 from I found that this tool can help me to migrate vhd file to VMware server easily (Very Easy).








Complete convertion.


You can find converted file in your defined path.


Add this VM to VMware datastore.
