Xen devel - Mar 2007 - Running Windows 2k3 guest in ACPI multi-processor HAL mode (acpi=1)

Hey guys,

I''m using standard openSUSE 10.2 Xen installation and would like to
start a
Windows 2003 Server as guest with SMP support. So Windows would have to be
in ACPI-Multi-Processor HAL mode to support SMP correctly.

Unfortunately the virtual machine crashes every time I try to start the
installation of Windows with acpi=1 in the hvm configuration file. The blue
installation screen appears and a few seconds later the machine dies, I
guess it is the time when Windows Setup loads the ACPI supporting driver.

Installation with acpi=0 just works fine but of course the later machine has
no SMP enabled and therefore is not able to use the 4 assigned processor
cores. I just tried to replace the hal.sll in c:\windows\system32 with the
correct one with ACPI-SMP support and changed acpi=0 to acpi=1 in the vm
configuration file. Still no luck, the machine dies right after the windows
bootscreen appears :-(

So, how can I solve this?
Would it be better with Xen 3.0.4 as the openSUSE 10.2 standard is still
3.0.3 (with some modifications from Novell I think)?

Thanks a lot for your support!


Regards,

Julian Pawlowski

Actually I''m just about to do so but having problems installing Xen
3.0.4

I''m now running Novells Xen preview for SLES10 (based on Xen 3.0.4) on
SuSE
Linux 10.1 successfully with acpi=1 and Windows 2003 Server as guest system.

Thank you guys :-)
