It could be a very interesting project, but I don't think that this
project and the xen ports are exclusive,

For the moment I have just had a quick look at linux kvm and at VTX
instructions.

It's not that I am not up to it or that I think that I am not able to
do it, but I will probably need more help and more mentoring to
implement a kvm-like subsystem than to port dragonflybsd to xen.
