So, what's the issue? I've seen your other thread, but it ends up with
you pasting a message that suggests xenstored is working fine, and in
general I could not figure out what the problem is from there.

FYI, for may day-to-day testing of my development work on Xen, I use a
Debian Sid host.

I configure Xen with this:

./configure --prefix=/usr/local --enable-systemd --disable-qemu-traditional 
--disable-stubdom --with-xenstored=oxenstored

I create a .deb package with `make debball' (because I build on a
different machine), ship it and install it on the test box.

This is what systemd sees:

root@Zhaman:~# systemctl |grep xen
