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
