[Xen-devel] Re: [ PATCH 2.6.16-rc3-xen 3/3] sysfs: export Xen hypervisor attributes to sysfs

I doubt that there is much that different hypervisors can share.
Why should all this be visible for user space anyway? What's the purpose?

In Xen at least, hypervisor management and control programs run in user space in a "privileged" domain (or virtual machine). Systems management agents in user space on the privileged domain need to know this information, and sysfs is a good place to expose it.
