virtualbox.org

I have vbox-ose running in amd64 jaunty and a 32bit guest xp image. kvm / libvirt is installed but I disable kvm modules when using Virtualbox.
Goal is to have one xp image that runs in both virtualbox and kvm, the former by disabling the kvm extension (module unloading).
I converted a raw image via qem-img to v6 vmdk image which is usable in most virtualisation environments.

I made 2 tests:

1. I had a XP image which works fine in qemu/kvm. When I try to run this image in virtualbox it doesnt start.

The selection screen arises:
Only ACPI is enabled

After selecting an entry windows freezes.

2. I created an xp image with virtualbox which works fine in vbox but refuses to start in kvm.

Without posting further details, is this an error in use of different guest hardware? Is it possible to use qemu/kvm images in virtualbox?

EDIT: Changed title, descritption a bit.

Put this in google.com
qemu/kvm site:forums.virtualbox.org

dont find anything in google related to reusing a qemu xp image in virtualbox and vice versa.

Somebody can shed some light on this?
Is there some hardware incompatibility between qemu and virtualbox? The strange thing is it freezes immidiately after choosing one of the windows bootloader options.
