Description Mor 2017-06-26 02:25:37 EDT
Description of problem:
ovn-controller service is not shipped as enabled (to start at boot), by thus can cause a VM to fail if it has OVN network attached to it after a reboot to the hypervisor.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. on hypervisor, run yum install openvswitch-ovn-host
2. systemctl status ovn-controller

Actual results:
Loaded: loaded (/usr/lib/systemd/system/ovn-controller.service; disabled; vendor preset: disabled)

Expected results:
ovn-controller should be enabled by the RPM installation.
Comment 2 Lance Richardson 2017-06-26 08:25:31 EDT
My understanding of packaging guidelines is that only services that do not
require configuration to be functional may be enabled by default. Since
ovn-controller requires configuration in order to be functional, it should
not be enabled by default. See e.g.:


Your application must already be doing the equivalent of "systemctl start
ovn-controller" in order to use this service, is there a reason it cannot
also do "systemctl enable ovn-controller"?


Comment 3 Mor 2017-06-26 09:01:09 EDT
Dan, could you answer this?  On hypervisors - can we change the code of the hook(s) to start ovn-controller service?

Currently, the only thing that triggers ovn-controller start is vdsm-config, which is only used only once during setup of the environment.
Comment 4 Flavio Leitner 2017-06-28 08:24:43 EDT
We also don't enable OVS by default.
Comment 5 Dan Kenigsberg 2017-06-28 16:38:25 EDT
I agreed with Lance. Services should not be enabled by default, without a very good reason.

The bug should have been filed on ovirt-provider-ovn-driver.
