Thank you in the name of all team that develop OpenNebula

Not, not yet, but you can use "onevm top" for Virtual Machines and
"onehost top" for Physical hosts

At this time OpenNebula don't choose between hypervisors, but would be
easy to add a script that checks what kind of hypervisor is running in
every resource host and add a field in the template file that use this
field as a requirement to send this VM to a resource host.

Modifying files: xen.rb and kvm.rb (im_probes/ruby) adding the line

puts hypervisor=KVM (in kvm.rb file)

puts hypervisor=XEN (in xen.rb file)

No, but is useful to use like history
