Due to the lack of a proper way to describe all the dependencies within libxl I suggest to revert these commits for the time being: 278c64519c libxl: fix libxl_domain_need_memory after 899433f149d 899433f149 libxl: fix migration of PV and PVH domUs with and without qemu 3802ecbaa9 libxl: add helper function to set device_model_version Olaf
