Good! I've been strapped for time, but will eventually get around to it perhaps. Mike Day's been doing excellent work on it. I think it would be nice if the attribute were called uuid and not vm with "/vm/" prepended. I suppose it's fine to keep "vm" as a shortcut, but a separate UUID attribute is more important, IMHO.
Peace.

We have a sysfs framework for Xen (xen_sysfs.c) submitted from IBM and in our tree. Having a uuid attribute in there sounds fine to me -- feel free to make a patch! You can get the uuid from xenstore as Gerd described, or add a version hypercall to grab it.
