how is this a property and not part of version?
Agree, changeset should be part of version

again what is the justification of putting this in the kernel? I though
everyone here was agreed that since the management tools that need this
talk to the hypervisor ANYWAY, they might as well just ask this
information as well....

I think we had a good discussion but short of agreement. Some tools want to read a file from /sys/hypervisor/ rather than call a c lib. (In other words, not all tools will talk to the hypervisor.) It is appropriate to view the hypervisor as a hardware device so it is appropriate to have some information in sysfs. I appreciate the counter argument as well, but think this should be a configurable option. thanks,
Mike
