Gianluca, due to all the twists of this thread, I no longer recall which libvirt version you are using. Would you remind us? All signs show that it starts up qemu without setting its auxiliary group properly (Assuming that your # groups qemu qemu : qemu kvm is just as mine) I've added libvir-list so the fine folks there could check why qemu cannot read/write files group-owned by kvm.
