   Hi Roger and thanks for your time and efforts.

   I thought XENBUS_PATH was some sort of a reference to the xenstore
path of the VM being executed and that the libxl would export that to
the hotplug scripts. I thought that simply allowing the libxl to execute
hotplug script for blk devices would be enough.

   Can I be of any help? Feel free to pass me work I you're busy.

   OTOH, I wasn't aware it could involve the Dom0 kernel. I'm confused
about that, could you please explain me why it does involve the dom0
kernel?

   Thank you,

   Gus

   PS: a bit offtopic, but I've been reviewing the commits to FreeBSD
HEAD and I don't see this:

         https://people.freebsd.org/~royger/mem.patch

   IIRC that patch solved the problem of domU PV guests with some
hardware. Could you commit that upstream?
