I haven't done the move to R2 as you did, but simply re-created my VMs by
creating a new VM and pointing to the existing VHDs, and I'm not seeing this
issue. When you create a new VM with R2, it automatically includes a SCSI
controller, and this at has hot add of VHDs enabled. Just as a test to see
if there's something happening because the VM originated in the original
Hyper-V server, I'd suggest doing a test on one of the VMs by deleting it,
and then add a new VM pointing to the old VHDs.
