I'm running through some bugs with my Xen->XenServer work and just ran across the HYPERVISOR_VERSION being the Xen version and not the XenServer version. Does anyone know why that is? Given that feature/function in XenServer is tied to the XenServer version, I see using the Xen version as a bug waiting to bite us. Since I don't want to break API compatability, I'm not inclined to change it for this work, but do wonder if we shouldn't change it when the API revs next.
Thoughts? -tim
