Bugs, which
Windows XP does not allow changing from non-acpi to acpi hal:

and
http://support.microsoft.com/kb/309283
But as a workaround you can go to
Device Manager -> Computer -> MPS Multiprocessor
and update the driver to Standard PC.
This will give 1 idle processor
Downgrading to confirmed/low based on that : this bug is fixed in virt-
manager, but KVM could still refuse to try to do multiple VCPU when ACPI
is disabled (rather than trying and failing at it).

I believe this is a known issue for Windows XP VM's.
Do you have hardware virtualization?
Many older CPU's do not have support for virtualization and this is known to
cause Windows XP x32 VM's to run the processing power all the way up. Vista
and XP x64 have support for 'lazy IRQL' which allows

Well, that's just silly:

Then kvm should refuse to try, surely?

I found a solution to the problem in Jaunty.
To use SMP efficiently with Windows you need the ACPI Multiprocessor HAL
profile. It seems you can only get it during the install if Windows
detects that your HW fits that profile. The only solution I've found so
far is to reinstall with ACPI enabled an

Marking this bug against virt-manager.
If you disable ACPI, you can't do SMP.
This has been fixed in upstream virt-manager. The fix should be
relatively small, which would stop disabling ACPI on WinXP guests by
default.
