Description of problem:
"virt-top --help" and "man virt-top" offer no information on how to connect to a
kvm or qemu session. There's a "see-also" that points to virsh, which does have
the information; but it would be convenient for new users with kvm if they
didn't have to hunt so hard for the syntax to make virt-top usable.
This is now fixed upstream in this cset:
and this fix will therefore be included in the next release
of virt-top in Rawhide.
