Hyper-V, SCVMM 2008 and Failover clustering volume GUIDS

I have about 25 VMs on Hyper-v in a 4 node Windows 2008 Failover cluster.  I created the first 6 or so VMs before I learned about using volume GUIDs instead of drive letters.  How can I successfully change the existing VMs using drive letters to use volume GUIDs.  I learned the hard way that you simply cannot go into Failover Clustering and change the drive letter of the shared storage object since when the VM restarts, it no longer finds itself and getting it back is a difficult process.

I hear there is a possibility of manually editing the XML for the VM, but I also understand this is not a supported option and I am not sure it would work anyway.

your best bet to take the safe side is to migrate them to another host that is not in the cluster. Fix the GUID on your cluster and migrate it back.

Also to add to this, delete all your snaps. shutdown the VM and let it finish the merge. Backup the VMM files. Delete the drive, create a new GUID an move it all back to it and add a new virtual machine and reconfigure your VM settings.

What a pain.  Not worth it.  I will leave these at drive letter for now until Microsoft comes up with a quick way to change it.

This is what I have done in the past...
- Shut down the VM.  
- Using Hyper-V Manager, Export it to a new location
- From a command prompt, use Mountvol to list the GUID associated with the drive letter that is being used.  Copy the GIUD path.
- Remove the drive letter from the volume using Disk Management
- In Hyper-V Manager, start the Import process
- Use the GUID copied above as the target location
**TIP:  If you add an extra backslash to the end of the GUID path you can click Browse and browse the directory (it works elsewhere too).
- Complete the import process and start the VM.

HTH!
