Usage documentation is on [qvm-service manual page ](/doc/dom0-tools/qvm-service/ ). There are also described predefined services.

Under the hood enabled service in VM is signaled by file in /var/run/qubes-service. This can be used to implement almost enable/disable **per-VM** switch controlled by dom0. Adding support for systemd services is pretty simple:
1. Disable old service: `systemctl disable <service name>`
2. Create `/etc/systemd/system/<service name>.service` file containing:

.include /lib/systemd/system/< service name > .service
[Unit]
ConditionPathExists=/var/run/qubes-service/< service name >
2015-09-26 19:00:33 -04:00
~~~

3. Enable new service: `systemctl enable <service name>` .
This will cause service to be started only when you enable it with qvm-service for given VM.
