Not sure if the comment is correct, but based on Comment #9 to my bug
report, Debian/Ubuntu seems to package Xen in such a way that certain
components (such as libxenlight.so) are installed differently compared
to other distros.  See Comment #9 at
https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1180281

I haven't spent much time with virt-manager on Fedora 19 beta, so I
can't provide details.  But if I recall correctly, I also got
something like "Unable to connect to libvirt" when attempting to use
virt-manager with Xen and the XL toolstack.  XL was definitely
running, and near as I could tell, XM/xend was not running.  I didn't
try virt-manager with the XM toolstack.
