As you are using the git version it's pretty simple:

You need to fetch the branch containing the patches:

git fetch git://git.pipo.sk/libvirt.git virtualbox-4.2

and then create a new branch from FETCH_HEAD:

git checkout -b virtualbox-4.2 FETCH_HEAD

and then you need to compile it again. Make sure that the summary after 
configure ends lists the virtualbox driver.

Hm, there's a possibility that the package is named differently in 
debian based distros.

The inability to verify the DTDs shouldn't be fatal. Anyways, you don't 
really need to do make install from the git tree. You can run libvirt 
directly from the repo after it's built
