[Xen-users] Issues with drive recognition and qemu-xen under xen 4.3.0

[David Sutton <kantras@xxxxxxxxx>]

I'm running xen-4.3.0 under an ArchLinux dom0, trying to start a windows 7 HVM (using qemu-xen + SeaBIOS) and it seems to be failing to see the boot drive correctly. If I change over to using qemu-xen-traditional, then it works without issue.

From the logs, when it fails:

My disks line is:
---
disk = ['/dev/vg0/lvWindows,,hda','/Media/ISOs/OS/Win/7/Pro/64/X17-59186.iso,,hdc,cdrom']
---

Any thoughts?
