qemux86 and qemux86-64 have been updated with
support for KVM, paravirt and virtio drivers.
linux-yocto_3.4.bb recipe have been bumped to 3,
as two changes went in (was previously at 1).

    KVM, paravirtualization and virtio drivers are now activated
    in runqemu using the kvm option flag for qemux86-64.
    Host CPU features are also exported to guest OS (Yocto Linux).
    Usage example: runqemu qemux86-64 core-image-x11 kvm

    Implements [YOCTO #2550].

Please ignore this patch.
Do not merge it, it was a left-over.

Thanks,
