The libxl driver does support virConnectListAllDomains.

Well, like I said before, libvirt won't know about domains you created
with xl.  Unlike the old xm/xend toolstack, libxl is stateless and does
not support the notion of persistent or managed domains.  Applications
using libxl (e.g. xl and libvirt) provide state and don't necessarily
make that state available to other libxl applications.

Is libvirtd running as root?

Sounds like you should file some bugs with your distro.
