Re: [Xen-devel] Re: hvmloader/xenbus.c: How to modify or add a key-value pair in xenstore

Many thanks to all of you.
I see there are some functions in mini-os/xenbus/xenbus.c, such as xenbus_write() and xenbus_rm(). All of them seem to change the keys and values in xenstore. I have tried these functions and found that they have no effect on the keys and values in xenstore. So, do these functions can really work? What special things need I to do to make them work?

It is quite common for keys in xenstore to be ro for the guest (only the
backend or toolstack domain can write to them).
