Hi, The intention here is to boot every disk volume using the virtual Hyper-V SCSI adapter? That would be different than the procedure for setting up VM guest disks (on Windows systems only?) as described in Microsoft's Hyper-V docs, but maybe that is the goal.

I can try this early 12.04 code out too on a Hyper-V host. I am using Ubuntu 10.04 as a guest OS quite a bit on Hyper-V hosts.
