kvm-55 test

[Farkas Levente]

hi,
after we test kvm-55 no regression found to kvm-54, but 32bit guest on a
64bit host still not working (but now the boot process hang earlier the
starting udev). another strange thing that win xp with 4vcpu guest still
 see onlu one cpu inside the guest.
setup:
- host:
  - Intel(R) Core(TM)2 Quad CPU Q6600  @ 2.40GHz
  - Intel S3000AHV
  - 8GB RAM
  - CentOS-5.1
  - kernel-2.6.18-53.1.4.el5 x86_64 64bit
- guest-1:
  - CentOS-5.1
  - kernel-2.6.18-53.1.4.el5 i386 32bit
- guest-2:
  - CentOS-5.1
  - kernel-2.6.18-53.1.4.el5 x86_64 64bit
- guest-3:
  - Mandrake-9
  - kernel-2.4.19.16mdk-1-1mdk 32bit
- guest-4:
  - Windows XP Professional 32bit

You may need to update the Windows HAL to the 'ACPI Multiprocessor' or
something like that.

Do not meddle in the internals of kernels, for they are subtle and quick to panic.

A good way is, to install a new windows guest using acpi and -smp 4. The
windows installer will then select a multiprocessor kernel/hal. You also
can force a specific kernel/hal when pressing F5 during the
installation, when asked for pressing F6.

If you do not want to install a new Windows guest, you may

1. Extract from %SYSTEMROOT%\ServicePackFiles\i386\sp2.cab
halmacpi.dll
ntkrnlmp.exe
ntkrpamp.exe
to %SYSTEMROOT%\System32

2. cd %SYSTEMROOT%\System32
copy halmacpi.dll hal.dll
copu ntkrnlmp.exe ntoskrnl.exe
copy ntkrpamp.exe ntkrnlpa.exe

3. Reboot and let Windows do its magic.

4. Reboot when requested to do so.

5. Enjoy MP support.

I did it once (XP SP2, 32 bit) and it worked okay - but I don't know 
whether it will always work that way.

You can also try the following:

Download the devcon utility form Microsoft (free) and do the following:

devcon sethwid @ROOT\ACPI_HAL\0000 := +acpiapic_mp !acpiapic_up !acpi_up
!e_isa_up

# if the current hal was e_isa_up (no acpi, up) do also the following:
devcon sethwid @ROOT\PCI_HAL\0000 := +acpiapic_mp !acpiapic_up !acpi_up
!e_isa_up

# anyhow do the following
devcon.exe update c:\windows\inf\hal.inf acpiapic_mp

Good luck...
