kvm XP P2V required ACPI->Standard PC HAL change, keep or revert to ACPI?

[Jeff Kowalczyk]

I'm running a physical-to-virtual Windows XP Dell OEM instance on Ubuntu
8.04.1 kvm-62 with kvm-intel and bridged networking.

After early BSOD difficulty with the output of VMWare Converter
3.0.3, I did manage to get the XP P2V instance ready to run under
kvm after changing from the Windows XP HAL ACPI to "Standard PC" in device
manager under VMWare Player.

After a complete redetection of system hardware and resources (perhaps
this was the true reason it started to work), the instance must now be
activated again. It works very well, but must be shut down at the "You may
now turn off the PC".

This is a headless kvm server for a few straggle windows apps, and the kvm
instance will seldom be rebooted.

Should I activate as Standard PC, or attempt to convert the HAL back to
ACPI.

Is there still any performance penalty for ACPI with kvm-62?

What is the kvm shutdown behavior with an ACPI HAL?

Thanks,
Jeff

Basically it should work. Maybe newer kvm will encounter less problems.

Since we have the tpr optimization it should be fine. Nevertheless we 
did measure about 10%-20% performance
penalty on windows acpi.

It should be fine and turn off the process completely.
btw: you can install APM module on the standard HAL too and it power 
down the VM to exit completely too.
