hi, Keir:
Now i am studying the source code of Xenbus (version
3.1).
I found that, in "xenbus_init()", it seems the
xenbus need allocate a page for xen_store_mfn in Dom0, while in DomU the value
of xen_store_mfn can be obtained from "xen_store_info". So, i guess that every
domain has a machine page for xenstore-ring-buffer, that is xen_store_mfn. But,
i am puzzled as follows:
- if xenbus is the client, is xenstored in Dom0
the server, and is xen_store_mfn the communication channel between
them?
- where can i find the allocation for
xen_store_mfn?
- is the xen_store_mfn different for per
domain?
- can i switch off the communication between
xenbus and xenstored after i successfully logined into the
DomainU?
thanks a lot!
