Ken i'm glad your migration worked out I'm thinking of doing something similar and I had a couple of questions. did you have any issues converting the x64 VMware images to x64 Virtual Server/Hyper-V images? How long did the conversions take on average in terms of GB/hour? Thanks Sandy

Hey Ken, I just stumbled across your article. Very interesting! Thanks for the info! What kind of hardware are you running everything off of?

Hi Sandy,

The tool I used just rewrites one file as another. I think I was getting about 1-2GB/minute going from one SATA disk to another.

There was no additional issues converting the x64 machine that I had (for Exchange 2007) above converting the x86 machines. In essence all i was doing was converting the virtual disk files from one format to another.

Hi Caleb,

I'm running everything off a Dell PowerEdge SC1430 (Quad Core, 8GB RAM, 4 disks running off a 3WARE RAID controller)

Thanks for the response Ken! I lost your url and finally was able to find your site again. Its bookmarked now! I'm actually doing a conversion of an SBS2003 server to Hyper-V and I am going to try out your approach from going from a vmware file to a vhd file. I'm trying it out this way because the SCVMM2008 Beta keeps giving me errors when I try to convert the physical machine and it will never fully complete the job. Thanks for the info! How does your Exchange 2007 run as a VM? How large is your store and how many users do you have?... or is this strictly just a test box?

hi ken, thank you for this article. BUT ... "My VMWare machines were using SCSI disks connected to a SCSI controller. Unfortunately booting Hyper-V machines requires IDE disks at the moment. Since the IDE mass storage controller wasn’t set to start in my VMs, they Blue Screened with STOP 0x7B (Inaccessible_Boot_Device). I fixed this issue by inserting the OS setup CD and doing a repair on the OS" how i can do this REPAIR???

Were you able to backup your virtual machines while they were running?

Hi Lolli,

Insert your Windows OS CD (either the physical CD, or an ISO of the CD), and set your virtual machine to boot from the CD. There is an option, as part of Windows Server setup to repair an existing installation.

Cheers

Ken

Hi Tom,

Apparently there is an issue backing up virtual machines that are running Exchange Server. I've been able to backup another volume that just had Windows Home Server on it.

I did the conversion using the tool you recommended. And got the same blue screen error. I did the repair and it booted fine, but it hangs when I attempt to login. I can boot into safe mode and realized that the repair I did was with the original disc that did not have any service packs on it. The windows install, however, before the Repair had SP2 installed. I attempted to install SP1 in safe mode but it hangs on the Backing up files portion. Do you have any suggestions as to how I should proceed?

Hi,

If it's hanging when it's logging in, there might be some kind of networking issue (e.g. authenticating your username/password). The integration components probably aren't installed yet, so the networks are disconnected. Can you login using a local Administrator account?

If you need to repair again, the you can integrate SP2 into your existing source media, and create a new ISO image of your setup that includes SP2. Just google for "integrate Windows service pack" for instructions.

Hi Ken, I found out of a way to avoid the Blue Screen 0x7B error and doing a Windows Repair Installation. While you still have you VM in VMware add a second hard disk to your configuration. Any size will do as long as it is IDE based. Make sure that you select “Adapter: IDE 0 Device: 0" while creating it (otherwise you might end up with yet another SCSI disk). Boot your VM (while still under VMware and with both disks attached). Let it detect the new IDE controller, Primary IDE Channel and IDE hard disk (you should be able to see it as "not initialized" in Disk Management). If you haven't already uninstalled VMtools you might also do that now. Shut down your VM and do the vmdk2vhd conversion of your SCSI based vmdk disk (just delete the temporary IDE disk). When you boot the new VHD in Hyper-V it will boot correctly, detect all your devices and your Windows Installation will be 100% intact (still have to install Integrations Services and set your IP adresses though). It saved me for a lot of trouble with a SharePoint installation that Windows Repair messed up.

That's a great tip Steen! (and I'm smacking my head for not thinking of it at the time)

Hi Ken and Steen,

Thank you very much for this info, I have been consolidating Development & Test environments into Virtual and the performance was not optimal on VmWare Server, we are a Microsoft shop but VS2005 didn't support the x64 guests so I ran into problems and did not have budget for VmWare ESX server.

Created like Steen recommended a 1GB IDE disk then converted the vmdk files and booted it up in Hyper-V without any problems on the first virtual machine.

On the second one the converter gave me an error "Invalid VDMK file", so I googled so more and realized that VmWare server had splited up the hard disk files. So I tried the following scenario :

- Added a IDE disk 1GB and removed the VmWare tools

- Booted up VmWare Converter and converted the virtual server over to a new file share as a VmWare Server 1.x.x

- Was able to load the new vdmk file and convert with Vdmk2VHD

- Created a new Hyper-V, booted up and everything OK!

Took some time since I had about 80GB of data on the disk on the second Virtual Machine :-)

But everything is working and again, Thanks for these posts

Hi all, is there a way to backup a physical server and in case of disaster convert it to Hyper-V image to start it by Hyper-V. If yes is this way supported from Microsoft? The Hyper-V server should only be available as standby server. Thanks in advance AB

re: Converting from VMWare Server to Hyper-V RC0

Ken — Sat, 28 Jun 2008 12:54:08 GMT

Hi AB,

You can either use SCVMM 2008 (System Center Virtual Machine Manager 2008) or one of the other 3rd party tools (like Platespin), or simply an imaging tool (like Acronis ServerImage).

The main issue is injecting the necessary drivers - particularly the mass storage controller drivers (e.g. you may need to replace a RAID controller driver with a generic IDE driver). Most of these third party tools can do that for you.

I was curious if you ran into any trouble importing the virtual machines once they were converted with the VMDK2VHD utility? I'm running the same conversion process and I can't get the VMM Manager to recognize the new VHD files.

re: Converting from VMWare Server to Hyper-V RC0

Ken — Thu, 12 Feb 2009 04:27:49 GMT

Hi Andrew,

I can't say that I ran into any problems. Is Hyper-V MMC console telling you that the VHD files are invalid or something?

Cheers

Ken
