Hi,

I'm seeing a difference between the IDE and the SATA/VirtIO disks.

I dd'd a boot disk (Windows Dynamic Disk) image from a Windows 2003 R2 Standard server onto an LVM over iSCSI disk.

1. When I boot a Linux live CD with IDE, I see /dev/sda /dev/sda1 /dev/sda2
2. When I boot a Linux live CD with SATA I see /dev/sda /dev/sda1 /dev/sda2 /dev/sda3 /dev/sda4
3. When I boot a Linux live CD with VirtIO I see /dev/vda /dev/vda1 /dev/vda2 /dev/vda3 /dev/vda4

The four partitions seem to match up with my Windows Dynamic disks, while the two partition one does not. So, I have a problem:

1. Windows needs IDE to boot (before installing virtio)
2. KVM IDE doesn't see the right/all partitions.

So, I'm at a loss on how to boot this Windows KVM.

Any and all help appreciated.
