As little as it is worth, I'd like to send my +1 to this.

I totally agree with this analysis of yours.

And allow me to add that, for example, on Fedora 24, I have xen-4.6.4,
which does not have xm/xend.

And yet it appear I can install
libvirt-daemon-driver-xen-1.3.3.2-1.fc24.x86_64 which would be totally
useless and, from a user perspective, very confusing.

So, again, +1.

Dario
