Hmmm.... This is interesting. The XenExpress help says:
"The current version of XenServer supports no more than 3 virtual disks
(Disk0-Disk2) for unmodified Windows Xen Virtual Machines. The virtual
disks appear to the Windows XenVM as SCSI devices if the paravirualized
drivers have been installed, or as IDE devices if the paravirualized
drivers have not been installed."
and when I look in the Xen config for my Windows VM, the LVM partition
is exported as "hda", yet when Windows is booted (with PV drivers) it
reports that the C: drive is a Xen PV SCSI drive. Fascinating. I did not
look at what Windows thought the hardware was before installing the PV
drivers.
Can you boot the VM that you installed the PV drivers into if you change
the disk spec to be
disk = [ 'file:/Data/xen/bat-xp-scsi.img,sda,w', ...
? I removed "ioemu", since the PV driver will bypass the ioemu layer -
as far as I understand it. Sorry that I can't be more specific, but I
have only started using HVM this week so I am learning as well :-).
