Hi Michael --

Thanks much for your response!

"systemctl start xend.service" failed, "systemctl status xend.service"
revealed only very cryptic information... that's why I asked for
help, assuming that others might know if there was some missing magic.

In any case, since manual "/usr/sbin/xend start" works, I will
try to reproduce the systemctl issue sometime on a future install.

Thanks,
Dan
