self answer :)

before api error, there are http 400 error nova.api.openstack.wsgi [-]
http://localhost:8774/v1.1/admin/extras/servers returned with HTTP 400
When launced an instance using dashboard, openstackx.extenstions.admin.py.
And In create_instance() method, self._get_kernel_ramdisk_from_image(req,
image_id) is called.

But, real _get_kernel_ramdisk_from_image() method is in
nova.api.openstack.create_instance_helper.py. And definition is
_get_kernel_ramdisk_from_image(self, req, *image_service*, image_id).
Because of this, nova-api print HTTP 400 error. So I fixed
openstackx.extenstions.admin.py's self._get_kernel_ramdisk_from_image(req,
image_id) to self._get_kernel_ramdisk_from_image(req, image_service,
image_id). and instance could launched.
