Well, such "mounting" is going to be indirect, I would assume?
I.e. not directly forward filesystem like requests as such to
Xen?

For plain entries (reads and eventually writes) I surely would just
forward them. In case this is possible for directories, too, I'd rather
do no caching in the kernel, so forwarding them would seem to be
appropriate (rejecting anything but reading a directory, of course).

But that's still a kernel based file system, simply taking its
data from Xen. It's not like file system requests as such would
be forwarded.

True.
