The qemu-dm process runs without DISPLAY=0:0, which leads to a failure
if sdl is enabled.

Once I will try to find the time I will see if setting DISPLAY= will
actually help. xl.cfg(5) states that display= and xauthority= are
currently not handled anyway. And libvirt lacks such functionality as
well if I understand the docs correctly.
