Sorry, typing quickly, leaving out important information. :-)
I know very little about systemd, but I know that the Xen project
comes with systemd files which have been written by people who should
know, and that these are tested on a regular basis.
The xenstored.service file includes this line:
where other options for "type" might be "forking".
I also know that xenstored is explicitly coded to be able to detect
whether it's been run from systemd, and to Do The Right Thing in that

So what I meant was, "xenstored is designed not to do its own forking
