What:
====
It'd be great to be able to do something like:

'exportpath:/var/mypath/myvps1,/,rw'

so that the folder /var/mypath/myvps1 of a dom0 would be somehow
exported to a domU as /. Both the domU and dom0 would have read/write
access to it.

Why:
===
I know it is possible to do this with an NFS export on the dom0 then
access it from domU over network, but NFS is slow and has lock issues.
Using an LVM slice is ok, but then the space not used by a domU cannot
be reused by other VMs on the physical server, resulting in a lot of waste.

Also, on the desktop, that'd be great to be able to have a folder shared
between multiple VMs.

Many emulator have this option (for example some Atari emulators). Why
not with Xen too?

Just my 2c of idea, without even knowing how much effort would be needed
for an implementation...

Thomas
