This is a good point. I don't know what we want exactly here.

In the case of OVMF if you don't specify anything the default in Xen is
not to build it.
In the case of Seabios if you don't specify anything the default is
clone and build.

Do we want to be absolutely sure to avoid any cloning from the
xen-unstable tree with raisin?
Or do we simply want to fall back to the default behaviour?

I think that both a reasonable answers, I am leaning toward avoiding any
cloning always. This also means disabling stubdoms.  What do you think?
