Let me CC the maintainers.Andres really owns this code, so I'll punt to him for an official answer, but: - It's been listed as a 'tech preview' on the feature list since it went in. http://wiki.xenproject.org/wiki/Xen_Release_Features says: "Preview, due to limited tools support. Hypervisor side in good shape." - I can't say anything about SuSE's apparent support for it, except that ISTR Olaf worked at/for/with SuSE at the time. - Patches would, of course, be welcome. Tim.
