Perhaps worth checking with a xenstore-ls -p, or a xenstore-write attempt
within a domU, but the vm node should be owned by dom0 and read-only by the
domU. The recent xenstore permissions fixes should ensure that.
I looked with xenstore-ls -p but perhaps my test box is out of date.
I'll update it and see what it does then ...
Any progress on this?
Please note that there is a real problem with the current implementation
(xenstore_get_guest_uuid() returns NULL in stub-dom mode) that sometime
the ioemu-domain crashes while running a Linux HVM domain, So we should
fix it somehow.
Thank you,
 Yosuke
