Hi James,

I'm having a problem selecting which HAL to use.
Background :
I installed W2k3-SP2 with 2 CPU, acpi=1,apic=0,pae=0, and install Xen PV
Drivers 0.9.12-pre13. This worked fine. Then I clone this machine (using
dd, and using ntfsresize/clone), both method worked fine. Then I tried
changing the CPU to 3 (edit xen config, vcpus=3), this also worked fine.

Now I want to change the config to single CPU only (vcpus=1). Windows
crashed immediately during boot.

I tried extracting halaacpi.dll (according to
http://support.microsoft.com/default.aspx/kb/309283,
http://support.microsoft.com/default.aspx/kb/309283) to
c:\windows\system32, booted with /hal=halaacpi.dll, but still windows
crashed.

Any ideas? Perhaps I'm using the wrong hal?

Regards,

Fajar
