In XEN_DOMCTL_get_device_group case.


struct xen_domctl_get_device_group {
    uint32_t  machine_bdf;      /* IN */
    uint32_t  max_sdevs;        /* IN */
    uint32_t  num_sdevs;        /* OUT */
    XEN_GUEST_HANDLE_64(uint32)  sdev_array;   /* OUT */
};

XEN_DOMCTL_get_device_group is used by libxc.
sdev_array needs ot be handled correctly.
