VHD recovery

I had a Hypervisor running several vm's, then one day we came in and the hypervisor installation wouldn't boot and I'd lost my raid configuration in setup. I reset the raid and it saw all the drives and found the volumes I'd created. It then booted up but when it did, I had no network adapters or SR's. You can see the VLM and you can see the vhd's, but I couldn't mount them. SO...I had an external set of drives in RAID5 and these were data volumes used in the vm world, so I installed a fresh instance of 8.0 thinking that I might be able to read the vlm of the other set of drives, but no. I then was able to use a recovery that was able to read and see the vhds. I need help in restoring the orginal 8.0 installation.
