[Xen-devel] Windows XP ACPI Installation

["Guy Zana" <guy@xxxxxxxxxxxx>]

Hi,

I have a problem installing a Windows HVM with ACPI support (acpi=1).

Have anyone encountered this? What am I doing wrong?
I added some printks in order to debug the problem, note where esi
points to.

It happens in the phase where windows is "installing devices...".
Another thing, is the HVM 64bit?

Thanks,
Guy.
