be looking at instead?

Correct. We looked at adding code in hv_storvsc to handle CD/DVD

After reviewing this - I suspect the issue is the modifications to
ata_piix to prevent it from loading on a Hyper-V platform. Since
ata_piix now detects a Hyper-V platform and unloads if it's found, this
would prevent the OS from installing. We need a modification to the
patch here
What I thought was only a Client bug has also been confirmed on the

After some internal investigation, this is a known issue in the build of
hv_storvsc that is present in the Ubuntu kernel sources, including
3.2.0-16. The latest version of the driver, available in linux-next
after Feb 14 (at its new location in /drivers/scsi/storvsc_drv.c) has
that resolved, as
This doesn't change what the VM boots from - we still require that the
system boot from an IDE disk. What this does enable is our hv_storvsc
driver to control the root device, which uses hv_vmbus to communicate
with dom0. hv_storvsc and hv_blkvsc were merged upstream a while back,
and hv_storvsc
Andy, what's the correct process to try both the kernel-image and the

With the updated packages from apw, I've confirmed that hv_storvsc is

I've tested this, but it doesn't appear to work as expected. I installed

the driver as ATA instead of Msft as we would expect.

Can we get the drivers included in the initramfs? Without having them

older non-PV drivers (for IDE) and not have access to SCSI or network
