Have you tried virt-install/virt-manager?

AFAIR it was based off a random Linus remark.

More hackable, certainly, as any 20kloc project will be compared to a
700+kloc project with a long history.  More usable, I really doubt
this.  You take it for granted that people want to run their /boot
kernels in a guest, but in fact only kernel developers (and testers)
want this.  The majority want the real guest kernel.

One of the reasons is that if it is merge, anyone with a #include
<linux/foo.h> will line up for the next merge window, wanting in.  The
other is that anything in the Linux source tree might gain an unfair
advantage over out-of-tree projects (at least that's how I read Jan's
comment).
