This is actually a known bug: xen doesn't abide nographics
and tries to init SDL. This will almost always fail if
run through 5.2 libvirt. This bug will be fixed in 5.3.

What you can try in the interim is specify --vnc to
the virt-install command line. This should prevent the
guest from crashing, and you can continue as normal
with 'xm console' which should just work for a PV guest.
