Hi Akio,

That is an interesting idea.

I installed the HVM guest using the DVD.iso image as a CD and it worked fine, 
so I don't think that is the problem.

To verify, I just removed the DVD.iso reference, set vcpus=4 and rebooted. The 
same thing as before:

Loading sd_mod.ko module
Loading libata.ko module
Loading ata_piix.ko module
scsi1 : ata_piix

When I set vcpus=1, the guest OS boots fine. :-(
