In the other thread about the unsolved migration bugs in qemu-xen it became clear that "xen-save-devices-state" must not only be called for HVM, but for every domU that has qemu-xen attached to it. I wonder how to check for that fact from the migration code. While it can continue to rely on LIBXL_DOMAIN_TYPE_HVM make that call, for LIBXL_DOMAIN_TYPE_PV it is apparently not that easy. Is libxl__need_xenpv_qemu the API to use for the decision if libxl__qmp_stop/libxl__qmp_save/libxl__qmp_resume have to be called during migration?
