They look to be based on the Fedora ones which I wrote.

Fedora has the following systemd files (in xen-4.3)

proc-xen.mount - to mount /proc/xen

var-lib-xenstored.mount - to create a tmpfs mount at /var/lib/xenstored

xenstored.service - to start xenstored (if /proc/xen/capabilities exists)
and to set /local/domain/0/name in xenstore

oxenstored.service - the same as xenstored.service but to start oxenstored.
It conflicts with xenstored.service which means it should get started 
instead of xenstored if both are installed
blktapctrl.service - to start blktapctrl though I don't think it has ever 
been useful in Fedora and I intend to drop it when I build a xen 4.4.0 
package.
xenconsoled.service - to start xenconsoled

xend.service - to start xend

xen-watchdog.service - to start xenwatchdogd

xendomains.service - to run what is essentially a copy of the xendomains 
script with minor changes to take out the Fedora success/failure actions
which caused problems when I first wrote the systemd file. It might be 
possible to modify the xendomains init.d script so it works in both init.d 
and systemd contexts.
These don't try to start a qemu-xen instance as the current xencommons 
init.d script does, and we would probably need a xencommons.service to 
stop a xencommons init.d script being run.
