My kernel is : linux-image-2.6.22-3-686                                2.6.22-5
My kvm is :
ii  kvm                                                     48+dfsg-1
                Full virtualization on x86 hardware
ii  kvm-modules-2.6.22-3-686
48+dfsg-1+2.6.22-5         kvm modules for Linux (kernel
2.6.22-3-686).
ii  kvm-source                                              48+dfsg-1
                Source for the KVM driver

Modules are built module assistant.

Hope this can help you to improve kvm. Ask me If you need more informations.

Regards,
Thomas.
