Hi, I had a problem when moving my windows XP machine from the ACPI HAL to the standard PC HAL in order to get better performances (as pointed in http://kvm.qumranet.com/kvmwiki/Windows_ACPI_Workaround): on reboot the machine would just BSOD with kvm but work with -no-kvm.
The BSOD message was about intelppm.sys, so I did my homework, searched on Google and I found a page on Ben Armstrong's Blog: http://blogs.msdn.com/virtual_pc_guy/archive/2005/10/24/484461.aspx The very interesting part of the article is: "In the mean time we have made some subtle changes to the way our hardware exposes the processor in Virtual Server R2 so that in future products these drivers should never get loaded inside of virtual machines." Should similar tricks be performed in kvm? Btw, in case you wonder, changing the value of the key Start to 4 in both HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Processor HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Intelppm worked for me and the virtual machine is way quicker now.
