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
oclist
wbadmin01

wbadmin02

Step 2: Use the following command to add feature
ocsetup WindowsServerBackup
wbadmin03

Step 3: Check again to see if Windows Server Backup is installed
oclist
wbadmin04

Step 4: Use the following command to do system backup with system state
wbadmin start -backuptarget:p: -allcritical -systemstate
wbadmin05

Step 5: Backup completed
wbadmin06

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

Backgroud:

1. Download Hyper-V R2 SP1 from http://technet.microsoft.com/en-us/evalcenter/dd776191.aspx

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.

Problem:

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.

Solution:

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”

http://support.microsoft.com/kb/2517374

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