After the reboot the machine hangs right while the bootscreen appears. My current VM configuration had 4 VPCUs with acpi=1 and apic=1 and SP1 worked great. With SP2 I can only boot with a maximum of 2 VCPUs now. Maybe M$ changed something with their HAL in SP2 so that Xen needs a patch for it now. Cheers, Julian
