Change VM Location from Mount Point to GUID

I have a few VM's (running om Hyper v with all of the updates etc) that are using mount points for there vm location. Dedicated LUN per vm all mounted in a single "root" volume.
I am trying to make these VM's highly available I keep failing. The reason (i presume) is that Failover cluster on windows 2008 will only work with mount points if the "root" volume that they are mounted in is also failed over:

I would like to be able to perform quick migrations with out having to migrate all of the VM's at one time.

I could export all of the VM's and reimport them using the disk GUIDs but that would take quite a long time (large amounts of data per VM).

I am hoping someone might have a better idea?

thanks

Have you had a look at Hyper-V 2.0 (ETA October 2009)? I think this will include functionality to improve failover and live migrations, like ESX provides.

This isn't necessarily good advice for a production environment, but in a test environment is OK. When migrating from one Hyper-V Host to another if I know an export/import process is going to take forever then I copy the HDD to the new location and recreate the Virtual Machine on top and browse for an existing disk. I'd only do this if the machines were for testing purposes. Another drawback of this method is that you will have to reactivate Windows, but that wouldn't bother you if they were MSDN licenses.

Thanks for the comment but I was hoping to get this done before the "provisional" hyper-v 2.0 release date.
