xenbus_printf returned with errno=-13 ?

When I use xenbus_printf() in the kernel module of a virtual machine running on Xen3.4.3, the function returned errno=-13(Does it mean permission denied? I am not quite sure). But it works well when the hypervisor is Xen3.2.0. Anyone knows the reason?
Thank you
